We have Maytag DG312 -- oldy but goody. I have looked thru the threads here and elsewhere. The dryer will heat for 2-3 minutes, shut off heat, they repeat several minutes later throughout the cycle. It doesnt ever seem to get as hot as it used to.
We have replaced the coils and tested them after there was no change. We have tested continuity with wires removed to the flame sensor and the round thermostat (?) on the fire tube. both have continuity.
The venting is short using a flexible metal tubing.
Testing the thermostat in the vent tube got continuity between the purple lead and the yellow, but none between the orange terminal and either of the other two.
I'm stumped. Any suggestions are appreciated!
