I am not getting any voltage at the timing motor so I have to advance timer by hand. I measure 0 volts at the 2 timer motor leads. It heats up and cools down fine when advanced by hand though. Thanks for any helpfull information.
If you are not getting 120 vac between BK and TM on the timer then the timer itself is faulty and would need to be replaced as the motor feeds through the timer. That is if the unit is on time dry. If it is on auto dry then the cycling thermostat would most likely be the cause.
Gas dryer has intermittent heat. Burner comes on for approximately 2-3 minutes then off. Happens on all cycles. No lint build up. Cycling thermostat has continuity as does fuse.
With the cycling thermostat and thermal fuse checking ok and no lint build up to the outside of the home then the gas valve coils 279834 would most likely be the cause for the units gas shutting down prematurely.
Drier does not turn off on automatic setting. It does heat and run. The timer moves on a timed setting, but not on the automatic. I think it is probably the moisture control sensor, but am not sure where it is. Can you help me?
Answer Tanya, Your dryer doesn't have a moisture sensor assembly or control. Your dryer is an "auto advance" type system. The dryer has to have the proper temperature in the drum, to "cycle" the thermostat properly. When the cycling thermostat reaches the proper temperature and "opens" the neutral side of the circuit is rerouted through the gas valve and the timer advances. Since the timer advances on timed dry, the timer is not the issue. You will need to check the exhaust vent system and vent hood for obstructions and restrictions, that's the most common issue, improper air flow will cause the hi limit switch to open and "bypass" the cycling thermostat.
