I don't know where the color cables go on the timer pals shaft for my ge dryer

I'm sorry to hear that you're having trouble finding the color codes for your GE dryer. Here are the typical color codes for a GE dryer timer switch:

• Black wire: This is typically the power wire and connects to the hot terminal of the timer switch.
• White wire: This is typically the neutral wire and connects to the neutral terminal of the timer switch.
• Blue wire: This is typically the wire that controls the dryer's cycle, such as timed dry or automatic dry.
• Red wire: This wire is typically used for the dryer's buzzer or other signaling device.

However, it's important to note that the color codes may vary depending on the specific model and manufacturer of the timer switch. I would recommend double-checking the wiring diagram for your specific model, which should be located on the back of the dryer or in the owner's manual. If you're still having trouble, it may be best to consult a professional electrician or appliance repair technician.

Service manual and the wiring diagram is here, but Gas appliances should only be worked on by a certified gas technician. Working with upgraded or changed copy parts is a nightmare. Direction should come from North Pacific Timer, as they will know what the contacts do, and in conjunction with GE, they know what the wires do. The wires should fit into the same locations on the timer. Did you take a picture before you disconnected it?

got good used timer and any other parts you might need for that model. I live in citrus co. fl. 20.00 for timer is pretty good deal. I can even diagnose and install parts if need be. element 10.00 or if its the thermal fuse 2.50. let me know what you would like to do . I don't think it is the timer.

Maybe the knob is broken and slipping on timer shaft. If not, replace timer.

Runs but will not heat
1.loose wiring----check terminals & wiring
2.defective centrifugal switch in motor---replace switch ( check linkage to motor)
3.defective timer---replace
4.open heat element---replace heat element
5..defective operating thermostat---test thermostat, replace if defective
6.fan or it's pulley loose on shaft---tighten set screw
7.incorrect heat or timer settings---reset timer
8.clothes to wet when placed in dryer----wring out or extract water from clothes before placing in dryer
9.clogged lint screen or duct (little air motion)---clean out lint screen & duct

Clothes not drying, but dryer runs & heats
1.defective operating thermostat---test thermostat, replace if defective
2.fan or it's pulley loose on shaft---tighten set screw
3.incorrect heat or timer settings---reset timer
4.clothes to wet when placed in dryer----wring out or extract water from clothes before placing in dryer
5.clogged lint screen or duct (little air motion)---clean out lint screen & duct

you should be able to replace the knob from the front of the panel without removing the control panelit has a "D" shaft on the knob and shaft also has a "D" configuration too? right?

the clip that holds the fan on the back shaft of the motor may have broken so the fan isn't turning, check that , but first check the duct and make sure that you don't have a ball of lint clogging the vent,, also check the venting all the way out of the house,, clean the overhang of the outside vent cover, they get moist and collect lint

It could be a high limit overload, but the cause may be a blocked air vent. You can remove the dryer vent in the back and see if the problem stops, this will tell you if the vent is blocked or not. Ryan

You posted under GE timer, but added the brand name Intermatic.
GE and Intermatic timers are totally different.
Wiring below is for GE and will not apply to Intermatic.

Step 1) lets cover basic GE timer wiring for 240Volt load.
Be sure to set dip switches BEFORE applying power.
Step by step illustrations show on following link.
http://waterheatertimer.org/How-to-wire-GE-15207-timer.html

Step 2) Load wires exit GE timer.
There are two Hot wires and 1 bare ground wire.

Step 3) Wire the outlets: You have 4 240Volt plugs.
This could mean a receptacle-type outlet like a clothes dryer outlet or air conditioner outlet.
Or it could be a twist-lock receptacle or extension-cord-type stage plug.
In all cases, look at screw color on device.
Connect Hot wires to brass colored screws.
Connect ground wire to green screw.

Step 4) Calculate total Load
Manual appears below: Look at Normally Open contacts. These contacts turn ON when timer turns ON.
http://waterheatertimer.org/15087-15207-56922-Manual-eng.pdf
Total load on all 4 plugs cannot exceed 2 HP
Generally, a 30 amp timer is rated for max 24 Amps or 6 amps per each of the 4 plugs.
Volts x amps = watts.
Take total watts and divide by 240Volts to get amps.
