heat wont go off? what does that mean? turn the gas off and replace the valves if they're broken.

if you have change the thermostat it has to have the option for electric heat the thermostat has o turn the fan on in heat mode on air handlers

Probably a perished vacuum hose has collapsed or blocken, a bugga of a job replacing them. Check the ones at the engine first, it will be a small hose that disappeared throughthe firewall.

if you can't turn shaft by hand, motor sized or bearings(on both ends of shaft) shot.

Probably a bad door switch. See this file.

check breaker first it will run with the breaker tripped but it wont heat so turn off and on then check dryer for heat.dryers have a thermal fuse when they go bad it wont heat they are located on the element cage and are smaller than the thermostats.and if that is good then most likely element.but it usually helps to know what brand?

have you checked your fuses

the heating elkemnt may have broken and is laying against the housing forthe heatere causing the "short"

is this a gas dryer?
