Maytag Centennial gas dryer model MGDC 400VW0

[Thorning]

This dryer was given to me with the possibility it was not working properly. I dismantled it by removing the drum, cleaned all dirt out and checked all t-stats and the coils but found nothing wrong. The rotary dial control appears to be OK  I set it on timed dry and The igniter comes on, the solenoids click open, and the burner ignites but only stays on for a short time. I am not sure with the drum out if there is too much heat going to the t-stats to turn off the gas flow. It will turn back on in a few minutes.
Any suggestions or should I consider changing out the valve assembly ?  Need help ASAP.

Both of the t-stats on the heat duct were temporarily jumpered out of the circuits and the burner would stay lit. Looks like both will need replacing ?

If you are running the dryer with the front off, the burner will get too much air resulting with a lazy flame that makes the dryer cycle off because the high limit is being heated by the flame.
Put the front on and temp check at the exhaust duct in the back.

I put the drum back in and the front cover back in place but the lower t-stat on the heat duct tube still did not function properly. I replaced it and it now works OK. If possible both the t-stats will be replaced as time permits.
THanks for your assistance.

I didn’t look up this model to verify but if my memory serves me the upper tstat on the burner is a nonresettable thermal cut off. If that were bad you would get no heat at all.  And when buying that part it comes in a kit part number is 279816.  It will blow if the hi limit does not shut the heat off and it goes past the limit of the cut off. It kind of works just like the cycling tstat and thermal fuse just at a higher temperature. No need to replace the cut off if you have any heat at all.
