We have a Maytag LDG9304AAE gas dryer, about 15 years old. The dryer's heating element turns off after a few minutes. The drum and blower operate as expected, and in fact I just replaced the belt which did not fix the problem. Steps I've taken so far:

Checked the vent which appears clear.
Ran the unit with the vent disconnected (venting into laundry room); problem still exists
Looked at blower and internal vent - all seem clear.

To check the dryness sensor, ran unit on timer mode - problem still exists

To check thermostats, I disconnected each in turn and have continuity across the leads when the unit is cold.
BUT
I don't know how to check the high limit, and
There is one with four connectors; There is continuity between some but I don't really know how to test this one.

To check the coils, I read about 130 Ohm across the two leads for one, and across two of the three for the other,
BUT
I don't really know how to check the one with three leads.

Any help on continuing to diagnose this would be much appreciated.

bbruck- which one do you have ? Electric or gsa?? But to check the protector with violt_ohm meter :: you clip a prob from the meter to the two outer terminals:: no power on for the testing :: meter set to rxd! Scale; clip probs on the outer two terminals and if the meter reads ( zero ohms ) the protector is good< if it reads high it is faulty ( replace);; hope this helps <if not come back on to this post and vholler:: have a good day and god bless:: f.b.e.

Why are you yelling??

Thanks for looking.

Flying Blue Eagle, it's a gas dryer. When you say check the "protector", which element are you talking about? The coil? The high limit thermostat?
