Dryer tumbles fine, but not a hint of heat

[Gene]

There are five major electrical parts involved in the heating process:

1. Cycling thermostat
2. High limit thermostat
3. Igniter
4. Flame sensor
5. Gas valve coils

How to find out which part causing the problem?

Pretty simple: all of these parts have to be tested for continuity in the above sequence.

The following article on our forum will explain in detail how to run a continuity test using either an analog meter or a digital meter - How To Check Continuity With Ohmmeter

If any of them is open – it has to be replaced.

Gas valve coils also could be tested by resistance. There are two coils – one with three terminals and one with two terminals.
1. Coil with two terminals should have 1220 ± 50 Ohms
2. Coil with three terminals if held with terminals in upper position:
a) across the left and the middle terminals – 1365 ± 25 Ohms
b) across the left and the right terminals – 560 ± 25 Ohms

How to locate these parts in your dryer?

Type the model number (the name plate is on the door frame) in the search box, click the “search” button and you will be directed to the break down diagrams.

Using the break down diagrams, locate the part you’re looking for.

- The part number for the cycling thermostat is AP4037199

- The part number for the high limit thermostat is AP4036956

- The part number for the igniter is AP4037378

- The part number for the flame sensor is AP2910747

- The part number for the gas valve coils kit is AP3094251


Good luck.

Thanks Gene,
I found out after taking the front panel off, that the igniter was cracked. There was no continuety between the leads. I installed a new one aand the dryer works fine . Thankyou

You are welcome. I'm glad you were able to fix it.
