This one's kind of a hard call (for long distance); It is generally recommended that when you replace one thermostat or thermal fuse, just replace them all at the same time. Here's a break-down of the parts, showing the locations and part numbers. To check a thermostat with your multimeter, [COLOR="Red"]unplug the dryer.[/COLOR] Disconnect at least one of the wires attached to the component and check for continuity. if you don't find continuity, replace that component.

Bulkhead replacement parts for WHIRLPOOL GGQ8858HZ0 | AppliancePartsPros.com Thanks Magician59 for your feedback. This Dryer has 2 thermostadts. ( 3977425 Thermostat, Internal-Bias) and (3403140 Thermostat, 205 F (96 C)).Should both be tested? Since it does heat for a few minutes, I would guess the themostadt is closed at the beginning but how is checking the continuity (i,e, At room temperature, the thermostats should have a reading of zero) help? Sorry for all the questions but I want to make sure I am testing it right.

The thermostats may be weak. This is why it's such a hard call. Usually, when thermostats fail, they don't go out gradually. I would just replace them as a group, if, for no other reason than to make sure you don't have to gain access to that area again soon after the initial repair.
It could also be a weak coil causing the problem. The heat will cycle on and off, depending on the temperature, throughout the normal drying cycle. If a coil is weak, the flame will not re-ignite. Have you observed the igniter during the cycle? Does it glow, and just no flame appears? Does the igniter not glow, after the initial flame goes out? We're just trying to help you keep from throwing parts at your problem until something works.

Thanks again...since the heat WILL come on after I let the system sit and cool down for a few minutes... does that sound like the thermostadts or more the coil?

Run the dryer and don't shut it off. Let it go until the flame goes out the first time. Watch the igniter and see if it starts to glow after a few seconds. If it glows, but no flame ignites, replace the coils.

If it glows, but no flame ignites, replace the coils. Followed your suggestion with the following results: Opened peep hole in front of dryer to view igniter and burners. For the first 10 minutes or so... heard a click then the ingiter glowed and the gas came out and ignited. It cycled on and off a few times (which Im understand is normal) After about 10 minutes, still a click and the igniter glowed but no fire. Does that mean that the coils go bad after heating up or another problem (like the thermostadts)? Also, if it's the coils, are there any instructions anywhere as to how to replace the 2 coils?

It does sound like you have a weak coil. It's best just to replace the set (there are two of them). They're real simple to replace. The wire connectors just pull off; the bracket that holds them in place only has two screws. Remove the screws, lift the bracket away and the coils lift off. Just pay close attention to which one goes where. The whole job shouldn't take you more than ten minutes--if you can work through the inspection panel. [COLOR="Red"]As always: Be sure to unplug the dryer first.[/COLOR]

Thanks.... 1. Will ordcer two coils today....but 2. Should I replace the two thermostadts anyway or forget that? 3. What is the inspection panel? The front of the dryer is one piece (except 1" peephole) so do you mean to get to the coils come in from the back?
