Since it’s not heating on the regular temperature but however works on the Wash N Wear/Permanent Press temperature, likely the regular heat cycling thermostat has gone bad since that’s what is used all the time as opposed to the Permanent Press temperature. A new cycling thermostat will correct that issue, don’t need to get a OEM Maytag thermostat since the Supco thermostats are all over Amazon and eBay at the moment. Just be sure to replace it with one that’s rated for the temperature that the original regular heat thermostat is rated for.

Your welcome. If it was the heating element, it wouldn’t be heating on any of the other temperatures. Cycling and high limit thermostats are usually closed at room temperature but after many years, the bimetallic metal in the thermostats gets weak and sometimes to the point where it won’t really work anymore or will barely work. Gas dryers don’t have as many thermostat issues since there’s not much juice going through the thermostats as opposed to electric dryers since a gas dryer only has 10 to 20 watts of power going through the thermostat to the gas valve coils.
