Dryer runs but no heat. My husband is pretty smart with appliance fixes. Do you think that this thermal fuse solution would be easier enough for him to fix or should we get a repairman?

With gas dryers the unit will run with a bad thermal fuse, igniter, coils, thermostat or gas valve. check the thermal fuse for continuity. if the igniter does not draw enough amps the coil will not trigger the gas valve to open, or it could be a bad coil. pretty rare that the gas valve is bad. I would start with the thermal fuse, it is usually located on the blower housing.

probally the heeting element

First check the thermal fuse on the back of the filter housing.

Attached is a good troubleshooting video. I think that you will find that the Roper is the same as the Whirlpool and Kenmore
Note that the first thing that he does is to test the incoming voltage.
I suggest that you do this with the dryer running. I have seen breakers that will pass voltage without a load and as soon as a load is applied there is no voltage showing. As he says in the video the dryer can run on 110V as the motor is 110V however if it is missing the other leg of the 220V it can't heat. Another way that you could test this is to reverse the two incoming hot wires.

Good Luck.

Hi.

If the dryer runs there is no problem with power. If the appliance runs but does not heat the problem is one of the thermal devices. The dryer comprises one thermal fuse, several thermostats and the element. Thermal fuse and thermostats must be checked along with the element.

Start from the thermal fuse. The fuse can be tested reading impedance with a multimeter. If the fuse is open it will read Ohms infinity. In that case replace the fuse. Here the part: ASSY-BRACKET (THERMOSTAT) (Thermal Fuse with Bracket).

The fuse is part n.15 in Diagram one below. Click on the picture to enlarge:



If the fuse is OK, or if replacing the fuse did not help test the thermostats. You have the following parts:

THERMOSTAT - Part 11 in diagram

High Limit Thermostat -Part 13 in diagram

THERMISTOR - Part 27 in diagram

If the appliance is running the door switch should not be the problem. If you need test also the DOOR-SWITCH.

The thermostats can be tested reading impedance. If there is no heat, then one of the thermostats is open and will return Ohms infinity. Other way to test a thermostat is by jumping its contacts and running a controlled cycle to prevent overheating.

Check your thermal fuse. It is usually on the back of the dryer and you will not be able to see if it is bad or not. You can take out the fuse and attach a jumper to both contacts (Wire with two alligator clips) Or you can wrap the fuse with some thin stripped wire, telephone wire works great, just wrap around the metal parts on both ends then reinsert fuse. After you do this, try the dryer and see if the heat comes on. Do not run your dryer after this test without a thermal fuse, you can damage it. This is just used to test it. If your dryer starts heating go to an appliance parts store with your model and serial number and they can supply you with a thermal fuse. I think the last time I got one it was around $13.

Change your thermal fuse first. when thermal fuse goes bad either the whole dryer won't run or the heat element won't come on. Check out item # 3344 at www.repairclinic.com/Appliance-Parts?s=t-pye2300ayw-%3d%3d&z=100 If your thermal fuse is bad there will be no continuity through it.

if your vent is stopped up with lent your limit switch will trip and stop heating. you could have fusable link or even bad heating elements.

hi stella. yes the problem is with the thermal fuse. when you were cleaning the vent at the left. the thermal fuse is right there, on the air duct, a small piece of plastic with 2 blue wires to it . replace the thermal fuse . thanks the appliance doc

where is the thermal fuse located?

the power supply to the mobile home may not be strong enough {if generator run gen not big enough] {if powered by lead to power source lead to long or not big enough} {voltage drop}
