Recently my dryer stopped generating heat when drying clothes. All fuses are fine on the main circuit board, so I suspect the thermal fuse on the dryer itself has probably blown. We haven’t vacuumed out any lint build up over the years so it’s the part that seems most likely to have failed. I’m trying to perform a continuity test on the fuse, but I can’t seem to disconnect the fuse from the leads no matter how hard I tug on them. The leads use some sort of connector so I’m wondering if they’re “locked” onto the thermal fuse terminals?
I’ve attached a picture of the fuse with leads connected. Can anybody advise how to disconnect these leads? It used to be so simple …
See the attachment for the tech sheet.
I cannot tell if the connector is the lockable type or not from the picture.
Hopefully someone else knows.
In any case it probably will not matter.
If this is the thermal fuse from the blower assembly then it would kill power to the motor.
To kill power to just the heating coil a thermal cut-off (fuse) is used. It is item 47 in the Bulkhead Parts section.
Before checking anything else I would check the power to the unit.
The heater requires the full 240 volts, everything else runs off of 120 volts.
Try flipping the breaker off/on slowly a couple times, sometimes you can loose half the line without actually tripping the breaker.
If this does nothing, check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.

About getting those wires off. Just use a flat tip screwdriver. Slide the tip between the thermal fuse and connector and twist it and it should pop off. But if your dryer still tumbles then that is not the problem.
