SOURCE: Error code F3 on Kenmore 911.4658815 electric range
INGLIS Royal 100 STOVE F1 F2 F3 ERRORS
Mode lUP 48500 ( thats eye you, not ONE U )
I got the dreaded F3 error on the Display Panel,
every time I pressed BAKE or BROIL, BUT, I could
hear the three relays click in, and then kick out in
sequence, just before the F3 appeared.
I called Westinghouse ( that services INGLIS ) and
was told that F3 " means unpug for 1/2 hour and then
press CLEAR 5 Seconds to reset ". Which is nonsense.
All functions on the clock and timer work fine, and the
three relays were working, so its not a computer problem.
I called service REPAIR companies who said it was the
THERMOSTAT, and replace it - $147.99 ... The Glass tube
of the display is $200 with no circuit board, the relay board
is $300 and the computer/display is $400.
I did tests on the thermostat, first heating it with a propane
lighter, and it raised from 475 Ohms at room temperature,
to 600 ohms, so I knew it was functioning.
Then, I plugged in a variable resistor where the thermostat
plugs in. I went from Zero Ohms resistance to 5000 Ohms in
200 Ohms steps.
Zero Ohms ( equal to burnt out or unplugged) gives you
an immediate F1, which you cannot clear.
From 100 Ohms to 400 Ohms, you get Error F2, which
means thermostat too low.
From 400 Ohms to 665 Ohms there is no error.
At 665 Ohms, the BAKE will beep twice, stating that you
are setting the temperature at or lower than the actual temperature
of the oven ( you cant set the oven at 200, for example, if it is
already at 450 Degrees )
Using this 2 Beep code, I raised and lowered the resistance
and made a graph of the reading on the display versus the
OHMS that the thermostat would send to the controller:
665 Ohms = 170 Degrees Farenheit, which is the
lowest reading in the BAKE MODE.
800 Ohms = 240 Degrees
1100 Ohms = 380 Degrees
1400 Ohms = 500 Degrees, which iis the maximum that
the unit showed in the BAKE MODE.
1430 Ohms to 2750 Ohms, there was no reading, an NO ERRORS.
ABOVE 2750 OHMS, the F1 ERROR appeared again, meaning
thermostat out of range.
Note that the computer module supplies 5 volts DC to the thermostat,
to see the changes in current with changing resistance.
You can easily check the thermostat to see if it is OK, with an
Ohmeter across the thermostat, which should read about 475 Ohms
at room temperature. If it reads Zero, it is burnt out. If it reads
over 2750, it is defective. Check to see if the thermistor in the
tube is SHORTED to the steel outter case as well, as this should be
infinite ohms ( no contact )- if it reads ZERO it is shorted to case.
I found that on the Internet, there are hundreds of people looking for
the F3 code for the ROYAL 100 ( model number IUP 48500 )
and a general search shows that for 400 " other" models of all kinds,
F3 = REPLACE THERMOSTAT ! Not on this model, and all typical searches
for technical support or diagrams or troubleshooting did not even list
the Royal 100 AT ALL, as if it never existed.
I then did tests on the relay board, and replaced the capacitors, a few diodes,
some resistors that were a bit out of value, and two transistors that were
a bit out of value. There was no change in F3.
I cleaned the contacts on the three relays using a typical board fingernail
file that ladies use for their finger nails ( I keep a supply for cleaning
relay contacts, since there is sandpaper on both sides, and they are
tiny enough to fit between most contacts ). THEN, I realized that the BROIL
contacts were bouncing apart - they were too far apart, and not closing
properly, so I bent the stationary contact a bit closer, and plugged in the
stove = NO ERRORS..
I analysed the circuit, and after turning on the 3 relays ( NOTE, when you
turn on BAKE, as in a regular oven, THE BROIL ELEMENT goes on at first
to quickly help the BAKE element get the oven up to temperature )
there is a feedback circuit that feeds 250 Volts back into the 5 Volt computer
chip ( ! ! ! ) It uses two 22 Meg Ohm resistors in series for a total of 44 Million
Ohms, which shows about 46 volts accross the resistors. Since the gas
tube display uses 30 volts to light up, the 46 volts is within the computer
board's ability to lower it enough to feed into the computer. There are transisors
on the back of the control board and Zener diodes etc. to " compare " the
voltage, where 46 volts in = 250, and Zero volts, means that the element
is burnt out, the element fuse in the fuse panel is burnt out, or, the relay
contacts are dirty. The relays are absolutely standard 24 volt relays,
with a plasic cover that snaps off if you pull and wiggle it. You will see
the round silver contact pads are blackened and probaly pitted.
Sand these flat until silver/brass shiny, and test to make certain that
when you press the metal lever that the magnetic coil pulls DOWN,
that the contacts touch! If they do not touch tight, bend the
stationary contact in a tiny bit and test again.
You can first check the fuses - there are two 120 volt fuses in the
fuse panel that give you 250. Then, you can unplug the stove,
and use an OHM meter to see if the element is burnt. The two types
of elements I checked were 3000 Watt at 18.7 Ohms, and 2500 Watt,
at 48 Ohms. If the elements are burnt out, you will get ZERO ohms.
If the element is burnt internally through the insulation in the tube,
and shorting to ground, between the ends and the steel back of the
stove ( ground) you will get a reading of X amount of ohms ( which
normally should be ZERO ) If the element is burnt or shorted to
ground, replace.
The F3 error is a really dumb mechanical errror of whether the 250 volts
is on the elements. It does not involve the computer or the thermostat,
or the relay " electronics" at all - it is just simply 3 contacts that supply
250 Volts, and whether or not the contacts work, the elements work,
or the fuses work. This the same 250 Volts that is on an ordinary
dial stove, and the dumbest part of the whole unit.
When I called service, they said they would order the $147.95 temperature
thermostat, and " see if this fixes the problem", if not they would start
replacing the modules - $300 and $400, plus labour, plus tax etc., and
since the problem was on the module, this would cost $147.95 + $300,
plus $75.00 for the first 15 minutes, and $15 for each additional 15 minutes,
for a total of about $466 dollars ( CDN ) which is about $460 dollars US.
A package of 25 fingernail files is $1.00 at the dollar store. That is all that
it cost to fix the problem. You need a square ( Robertson ) head screwdriver
to remove the 7 screws on the back panel, and then you wiggle the
covers off the relays, and clean them. It takes 10 minutes.
good luck ! Damned the manufacturers for not putting this information
in the user manual.

SOURCE: F3 and F2 Error Codes
If hitting clear/cancel won't clear it try unplugging and then plug it back in. My guess is the oven control is bad. Here are the fault codes for this model.
Failure
Code
Condition
Check/Repair
F0 or F1
Failed transistor in control
If code cannot be cancelled, replace the Electronic Range Control (ERC) or touch pad
F2
Oven over temp - exceeded 590F with door in unlocked position or 990F with door locked
If actual temp condition occurred, look for welded relay contacts or high resistance connection or any cause in the oven temperature sensor circuit
F3
Open oven temperature sensor circuit
Measure oven temperature sensor circuit at oven temperature sensor (should be approx 1100 ohms at room temp); check for cut or pinched wire or loss of contact
F4
Shorted oven temperature sensor circuit
Same as above; check for melted connector or both leads shorted to ground
F8
Component failure within Electronic Range Control (ERC) effecting temp processing circuits
Replace Electronic Range Control (ERC)
F9
Problem with door lock circuit such as pinched wire between Electronic Range Control (ERC) and door lock switch
Check wiring and test operation of switch

Hi jacksmdmat,
Your f30 problem may be a bad sensor circuit. It may have an open connection or just plain defective sensor. Check the connection between the clock and the sensor as well as disconnect and measure the resistance of the sensor - should be about 1090ohms at room temp (75F)
SOURCE: Could you tell me what F11 code means?
F11 error code means there is a problem with the Control panel. Could be melted wiring, etc, since you left the oven standing. However, you can try unplugging the device from the power socket for about 5 minutes and reconnect. If the error goes away, then well and good; if not, you may have to replace the panel control.
SOURCE: LG RANGE LRE30451SB GETS ERROR CODE F1 AFTER OVEN
Here is some wisdom for understanding F1 fault codes.
In some models, there are subcodes that make diagnosis even easier.
Here's a simple explanation of what's going on and how to troubleshoot:
The F1 code indicates that:
a. The electronic range control (ERC) is sensing heat in the oven when in a time-of-day (i.e., not cooking) mode.
b. The ERC is receiving information to run multiple heat functions simultaneously.
Although different components (depending upon the model) could generate the code, simple and straightforward testing using your ohm meter is all you gotta do to test for it.
1. Check the oven temperature sensor. The oven sensor has to be within spec or it will cause the F1 code.
As an example of being out-of-spec, the ERC will generate an F1 fault code when the sensor shows 1650 ohms during a time-of-day mode.
This is equivalent to 350°F in the oven.
The resistance isn't high enough to generate an F2 code (runaway temp) or an F3 or F4 code (shorted/open sensor circuit).
The ERC monitors the sensor circuit after a heat cycle and expects the resistance to drop back to 1050-1100 ohms.
The fault code is generated when this doesn't happen. Checking the sensor circuit means also checking the harness,
harness connections and the sensor itself.
2. If the oven sensor circuit checks okay, then turn your inquisitive eyeballs to the touchpad.
If the range has a separate touchpad/keyboard, the keypad may have moisture that is shorting several circuits simultaneously.
If the F1 code is given immediately (instead of during or after a heat cycle),
remove the ribbon connector from the touchpad to the ERC after clearing the F1 code. If the F1 code does not return in five minutes,
then cast a suspicious gaze upon the touchpad/keyboard. Shorts may be caused by using an ammonia-based glass cleaner.
The touchpad surface will absorb ammonia-based cleaners that are sprayed directly on the glass surface. When heat is applied,
the surface material can break down causing shorts.
If you're gonna use ammonia-based cleaners on your control panel, then you should spray it on the rag and then wipe the touchpanel
-don't spray directly onto the surface of the touchpad.
3. On Amana ranges with a rotary temperature dial, be sure that the knob is in the OFF position when performing tests.
4. If these tests all check good, then replace the ERC.

I appreciate the post, dan moore!
From the information you have provided your Frigidaire range is displaying an "F11" error code. Typically, the "F11" error code stands for a shorted keypad. This could be a false error code and the best way to clear any false error codes is to disconnect power from the range for at least ten minutes. If you continue to get an "F11" error code you may need to replace your EOC (Electronic Oven Control), I would recommend having a professional technician come out to properly replace any electrical component to avoid personal injury. Hope this information is helpful to some degree. -Matt
Hi Ken Kazemi - Typically error code F11 indicates a shorted keypad. Try resetting the range by unplugging it or flipping the household circuit breaker off. This usually will clear most false error codes. Wait approximately ten minutes and if it proves to be ineffective contact a professional to move forward accurately. Most likely the EOC on the range will need replacing.
