Gas dryer starts to heat but stops

My Maytag propane gas dryer will call for heat , the igniter will get hot (red), the gas will flow, the gas will ignite, and then in about 2-5 seconds the gas flow will cut off. If the dryer is left on, it will spin and cycle through this sequence repeatedly, but never really get hot.

What needs to be done to fix this? Thanks.

The first thing I would do is check the vent all the way through the outlet and all air ducts inside the dryer, including the blower housing and the blower wheel.

Dryer is as clean as a whistle, including air ducts and vent pipes. Internal blower parts are also clean. Any more ideas?

Replaced coils and flame goes out in less that one minute

Hi.

What do you mean: "the flame goes out"? Does it ever ignites again?
Remove the vent hose from the dryer and run one load of laundry. See if that makes any difference.

Thank you.

Removed hose and ran dryer, flame went out while all else kept runnung. Replaced the coils and the flame still goes out after less that one minute. All else keeps running. Flame does not re-ignite.

Hi.

Does the ignitor cycling on and off with out the flame? If it does - replace the gas valve.
If not - check the flame sensor and hi-limit thermostat (both on the burner tube).
Use the time dry not the auto, does it make any difference?

Replaced the coils and then the flame sensor. Flame still goes out aft less than one minute. Tried the time dry and auto dry, neither mattered. Any other options?

Make sure the flame is being pulled through the burner assembly, if it’s just going up and hitting the top of the burner box then you have an airflow issue. Check your blower wheel, if it spins on the shaft without turning the drum then it’s worn out and will need replacing.

None of this may be it but i didn’t see any mention of it yet and just trying to offer some other things to check. good luck. let us know what you find.

Hi.

Did you check the hi-limit thermostat?
Put the temporary jumper wire on it and test run the dryer.
If it works - then either the hi-limit or air restriction.

I had the same problem, I opened up the front of the dryer and took an air compressor and vacuum and cleaned out everything really well (especially where the gas comes out) and it seemed to have fixed the issue.

Give it a try and see if it helps…
