I have a Kenmore gas dryer that runs and starts to heat, but shuts off in a minute or two and continues to blow non-heated air. Vents are clear and air flow is good. I noticed the glow tube does not stay on once it ignites the burner. Any ideas? Thanks.
You have a few components to check into, first off that igniter should be glowing the entire time the gas valve is opened, has to do with resistence to current. There is a small square attached to the flame tube called a "flame sensor" if it doesnt see the flame it won’t allow the gas to continue. You need to check that for continuity. also you can check the glowplug the same way. Its possible the gas valve is opening but closing because the coils are bad also.
Most gas models you can access directly from the lower access panel, few screws kinda at foot level. If you cant get to it that way, you will have to remove front cabinet assembly.
Also you shouldnt have to remove the drum , its all on the right side
If your dryer ignites only once and then fails to reignite, than most likely the problem is bad coils. Continuity test is not enough to be sure there is nothing wrong. More dependable is to test them by resistance at the time when the dryer does not reignite.
The coil with two terminal should have 1200 ± 50 Ohms
The coil with three terminals, if held with the terminals in upper position:
a) across the left and the middle terminals - 1360 ± 25 Ohms;
b) across the left and the right terminals - 560 ± 25 Ohms
These coils is one of the most common problem with gas dryers and I would just replace them.
The flame sensor is nothing else but a thermal switch which opens the circuit and switches power through the coils. The coils energizes and open the gas valve.Igniter lights up the burner, goes "off" and stays "off" until next call for heat. Power to the burner now controls by a series of thermostats.
- The part number for the coil kit is AP3094251

Gene,
You are a genius! I ordered the coil kit and installed it. What do you know; my dryer works perfectly! Thanks for your help, you were really on the money! Thanks again.
You are welcome. We are glad you were able to fix it.

We had a storm last night while we were out and our gas range was beeping a F5, I tried resetting the clock and would still go back to beeping the code. The oven turns on and everything works fine. Your online support has told me the manufactuer no longer makes the replacement part for the clock. We can’t find the owners manual to maybe reset it somehow. Help!
F5 on that model is suppose to indicate a failed electronic control. And yes the control part # 5303269513 (AP2140445) does look to have been discontinued and is no longer available.
If needed, you may be able to find a company to repair the original electronic control by searching the Internet.

Thank you Dan for this information. I did end up plugging the stove back in around dinner time and so far it has not beeped the code, everything works and it’s fine. Do you think it had something to do with the storm or is it just starting to fail on us?
It’s possible. Power fluctuations cause all sorts of problem with electronic controls. :rolleyes:
Good luck!
