Had no heat replaced heating element still no heat. Please outline steps and settings on a digital multimeter to check other components. What reading should I be getting across the heating element? Laundry is piling up! Thanks renttibw

Here is the wiring diagram

Other components (fuses and thermostats) all should be 0 ohms.
Note: That you cycling (control) thermostat will have 4 connections.
2 for the contacts should be 0 ohms
2 for it's internal heater should be 7,000 ohms approximately.

A couple things to watch when measuring ohms and continuity
1. Always remove power from the machine otherwise you could blow your meter.
2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path.
3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale's dynamic range.

There is a good STICKY at the start of this forum about it's use.

Also when checking for ohms I always short the meter leads together to see where true 0 is re: is the meter giving an offset..

Should be approximately 10 ohms.

First try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker and the heating coil requires the full 240 volts.
If this does nothing.
Measure 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 unit's terminal strip to ensure they are properly connected and none of them have burned off
If OK
Plug the unit in and check the voltage at the terminal strip. This is just in case you have a bad line cord.
[COLOR="Red"]Be careful 240 volts is lethal.[/COLOR]
