My Maytag PYE/G4500 dryer has blown it''s second thermal fuse since the first one a month ago. I jumpered across the fuse, (as I did the first time to determine if it was blown) and the drum light comes on, but when I turn the timer dial to a setting it blows the breaker without closing the door and pushing the start button?

Re: Matag Dryer won't run
If the thermal fuse is blowing or the breakers when you bypass the fuse it means a part has a short circuit. There are more than one thermal fuses in there, so you will have to find where the one that blows is connected to.
My guess at this point would be that the motor or the start up capacitor are causing the fuse to blow but also check for a defective or shorted heater element.

If it is completely dead, it is probably the thermal fuse. Without the model #, it's hard to say where it is or which type of fuse you have. you can check it with a meter or just jumper across it (just long enough to see if it turns on). Do not run it without the fuse as it can overheat and possibly start a fire. The blower motor blows across it to keep it cool , but if the dryer hose is clogged , the heat doesn't get out fast enough and will open the thermal fuse.
Here is a link to maytag dryer repairs http://apcoappliancerepair.wordpress.com/?s=maytag+dryer . The most common problem is the thermal fuse. My question is. Does the heating element start to light. If not...... and you have changed the ignitor and thermal fuse. Then check the flame sensor to see if there is continuity threw it. Power to the gas coils and ignitor runs threw the flame sensor. CLICK HERE to see a flame sensor on a GE dryer. They are the same on most units but Maytag will be on the opposite side of burner chamber.
Disconnect powerThat thermal will blow and kill power to the door switch circuit. The dryer will no longer function till you replace the thermal fuse. Failure to temove lint will cause continued thermal fuse replacement.
1. No power to the dryer Make sure there's power getting to the dryer. Check for tripped circuit breakers or blown fuses. An electric dryer uses two circuit breakers or fuses, and if only one of two is tripped or blown, the dryer might still run but not heat. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.
2. Heating element A burned out heating element will show no continuity when measured with a meter. Replace the element if found defective.
3. Thermal fuse Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.
1. No power to the dryer
Make sure there's power getting to the dryer. Check for a
tripped circuit breaker or a blown fuse. Check the wall socket for
power with a voltmeter or by plugging something else in.
2. Door switch / Door switch actuator lever
The dryer would not start with a broken door switch. Replace the
door switch if found defective.
Most dryers have a door switch actuator lever - when you close a
dryer door, it presses against the lever, which actuates the door
switch. If the lever is broken, the switch would not activate and
the dryer would not start. Replace the lever, if broken.
Note: Door switch actuator lever usually comes with the door switch
assembly and it is recommended to get the whole assembly since there
is almost no price difference between the door switch assembly and
just the lever. Check your model for more details.
3. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer
overheats, in which case the dryer will either not run at all or

broken or clogged, and there is nothing blocking the venting.
Note: It is recommended by most dryer manufacturers to replace a
hi-limit thermostat when replacing a thermal fuse.
Replace if defective (note: uncommon problem).
