Whirlpool electric dryer not heating. Assumed it was heating element and replaced. Dryer is still not heating. Any other ideas on what could be wrong. This has been a very good dryer and I don't want to replace.:confused:
Thanks rj trucks

When you replaced the heating element you should have seen thermal fusesand thermostats. Check them for continuity, particularly the thermal fuse. Make sure the dryer is thoroughly cleaned of lint, particularly in the exhaust vent and blower

Before doing that, check to see that you are getting 120 volts to each side of the connection block. Then unplug the machine to do the other checks.

Good luck.

If you will post the brand and model number of the machine someone should be able to help you. Please start a new thread and describe in as much detail as you think appropriate how the machine is operating. I am assuming that it runs but no heat comes out, and that this happens in all cycles.

If you do not own a meter, I would suggest you purchase a one. You can get a decent digital multimeter for under $20.00. You do not need fancy though it is nice if the leads are a couple feet long.
If it saves ordering one unnecessary part it has paid for itself and you end up owning a useful tool.
Most places will not let you return electrical parts so if you order it, you own it.
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.

Here is the wiring diagram
http://www.servicematters.com/d...0Sheet%20-%203393987.pdf

You could always borrow a meter.
As sidfink43 said you have to check the power first, could be there is nothing wrong with the dryer. The motor and timer run off half the line (120 volts) but the heater requires the full 240 volts.

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. Be careful 240 volts is lethal.
If OK
Unplug the unit and check the heating coil and thermostats etc. for continuity.
Heating coil, should be 10 ohms approximately.
Thermostats and thermal fuse all should be 0 ohms.

Be sure to disconnect one side of and device you are measuring this prevents reading an alternate/parallel circuit path. Also use your most sensitive ohms scale.
There is a good Sticky at the beginning of this forum on meter usage.

I have a Whirlpool model LEC8858DQ0. I went through the complete sequence with a meter and find no problem with power at wall or terminal strip, and continuity on thermostats, thermal fuse, or heating coil. The lint path is clean and I am stumped! Thanks for the tremendous help!

Please start your own thread using Post New Topic in the dryer section.

It will just get confusing trying to troubleshoot 2 different models even if the symptoms are the same

Thanks
