Parts for Frigidaire GLEH1642DS1 Washer Dryer Combo - AppliancePartsPros.com

Here is the wiring diagram

First check the power. The motor, timer etc, runs off of half the line (120 volts) but the heater requires the full 240 volts.
Try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker.
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.
Do this with the heater off and on.

Did you have 240 from L1 to L2?

Just checking each line in for 120 to Neutral is no good. As one side of the line can feed through parts in the dryer so you see 120 on each leg but it is actually the same side (phase) of the line.

Unplug the unit and check the following.

Next check the heating element, should be around 12 ohms.

Then check the hi-limit thermostat, should be 0 ohms.
If the hi-limit is blown you have to figure out why it blew before replacing it.

Then the control thermostat contacts, should be 0 ohms.

Then place the timer mid cycle of a heater timed dry cycle and check the timer contacts A to B, should be 0 ohms.
Be sure to disconnect the wire at on on the timer contacts before testing. This ensures that you do not read an alternate/parallel circuit path.


Also use you most sensitive meter scale when checking the above, usually 200 ohms.

I pulled the dryer all apart and found the element burned apart. Do I need to change anything else when I replace the element.

You should not have to change anything else but I would check the following: belt, idler wheel, rear support bearing, front supports, drum seals etc.
Might as well give it an overhaul.

Clean and re-grease the rear support bering using a high temperature grease.
Also a good time to clean/check your vent system.
