Question about Dryers
If you keep blowing the thermal fuse there is a air flow restriction some where disconnect the exhaust at dryer turn on you should have a good air flow exiting machine if not check the blower wheel for lint build up if good the it is in the exhaust exiting the house this is a rarity but the thermistor which cycles heat on/off could be bad hope this helps

I had the same thing happen, I replaced the thermal cutoff and made sure no lint build up. It lasted a week then blew again. I then replaced it again and got to thinking why it would blow. I then took apart the exaust inside the dryer running fron the drum to the motor and right before the motor was a build up of lint ane particals that was almost like compressed sawdust which was blocking half of the line. I cleaned this out and it seemed to work much better.

SOURCE: thermal fuse keeps blowing
Unless there is something restricting the ventilation I think you are having a problem with the heating coil staying on too long. If that is the case, one or more heating sensors are bad. Let me know if this helps and thank you for using FixYa!

I am not 100% sure, but I think that the model that maytag had with that dryer. When I was working for my local dealer I had to change several of those, and it about 2 weeks time they blew.

something is still plugged with lint,if the vent line is long blow it out with a leaf blower to clean it out,you have to clean out the duct that the lint filter slides into,if the filter is on top remove the vent line,remove the back panel,remove the lint filter and the two screws in front of it and remove the four screws and clean out the duct,if the filter is in front take off the bottom panel,remove the filter and clean the duct,also vac out the inside of dryer where the motor is,when the dryer gets to hot the thermal fuse pops as a safety so you still have a block somewhere

There are two thermistors (thermal sensors) in this dryer; one is the outlet thermistor located on the blower housing and the other is the inlet thermistor located on the heating element housing as an integral part of the high-limit thermostat.
These thermistors are negative coefficient type and monitors the dryer temperature on their locations according to their resistance which varies inversely with the temperature. The resistance drops as the temperature rises and rises as temperature drops.
One or both of the thermistors has an open connection or high resistance which makes the electronic control board thinks that the dryer temperature is low no matter how high it is. The electronic control board then doesn't cycle the heater relay and continue to turn on the heating element. The dryer temperature continues to rise and this blows the thermal fuse.
Make sure the thermistors are connected snugly. Remember that loose or open connection means high (infinite) resistance which makes the electronic control thinks of low dryer temperature. Measure the resistance of each thermistor then refer to the tables below. Replace the thermistor if the resistance reading doesn't comply with the table.
