Question and Answers


Why won't my Whirlpool gas dryer always heat and advance the timer?


First, the timer should advance in the time cycles regardless if the dryer will heat or not. Now, if the dryer does not heat during the automatic dry cycles then the timer will not advance. The timer motor will only begin running once the operating thermostat is satisfied. Which means it must heat and reach the operating temperature before the thermostat opens and completes the Neutral path to the timer motor.

Since you had to replace the thermal fuse once already is an indication of restriction in the venting system or too long a vent system. When the dryer can not vent properly it can cause the burner flame to short cycle. It will come on and go off before it reaches the operating temperature and also take longer for the flame to come back on again. It will also cause the thermal fuse to open and then the thermal fuse will have to be replaced again.

Check the thermal fuse connections to make sure they are good and tight or the glow bar igniter will not glow and open the gas valve. Make sure the ORANGE wire is making a good tight connection as well as the blue wires or it may not heat or advance when set to the automatic dry cycles. NOTE: Disconnect the power cord from the power supply before removing the rear panel to check the connections.

If the burner ignites initially and then shuts off rapidly then takes along time before the burner comes back on would lead me to believe that you may have restricted venting system.

For testing purposes only: Disconnect the vent hose from the back of the dryer and dry one load of clothes. If the burner stays on longer and cycles back on sooner then this would indicate a venting issue causing your problem and most likely caused the previous thermal fuse to fail.

Why does my Whirlpool gas dryer model TGDS740PQ0 only heat for ten minutes?


The timer not advancing in the permanent press cycle can be related to the not heating after 10 minutes problem.

If the dryer doesn't heat then the timer will not advance in the automatic cycle.

If the dryer will heat for ten minutes and then latter will heat again for 10 minutes then the thermal fuse is okay. An open thermal fuse will allow the dryer to run but an open fuse will not allow the dryer to heat at all.

When a gas dryer works for 10 minutes and then stops heating at all the most likely failure is with the gas coils or gas valve.

If you don't mind a little do-it-yourself detective work there is something you might try to pin this problem down.

There is a small plug in the front panel that can be removed with a small straight edge screwdriver. See the image below for a picture of the part key 49 plug. With the plug removed you should be able to tell if the igniter is coming on or if there is any flame at all.

One thing to know is that after 10 minutes and the dryer is not heating is if the igniter is coming on. After 10 minutes if the igniter comes on then the timer, thermostats and flame sensor are okay.

You should hear an audible click from the flame sensor and the igniter should shut off but at the same instant the voltage that was running the igniter is switched to the gas coils. If you hear nothing then most likely the coils are bad. If you hear a click, buzz or humming noise from the coils but there is no flame then most likely the gas valve is bad.

This check should help pin down if the problem is with the coils or the valve. One thing odd about the coils is that both together will cost approximately $78 dollars but you can order a coil kit 279834 with both coils for approximately $21 dollars. The kit can be ordered from the following link: Sears PartsDirect .

I hope this information helps to resolve this problem. You can submit another question with any additional details for further assistance with this problem.
