How do you check voltage to dryer?

Wondering, how EXACTLY do you check to voltage to the dryer? Is this done with a VOM and, if so, is it done while the machine is plugged in or what? I'm working with a Whirlpool model# LET7848DQ0, runs but doesn't heat up. Already checked the continuity on the heating element and thermal fuse.

    So, HOW do I check it?



    Do I unplug the dryer and use the VOM to check the outlet itself? Is this what you mean by "the voltage at the cord"?



    Sorry. . . but I did say, "how EXACTLTY do you check the voltage to the dryer?" This is indeed what I think needs to be done, I just don't know HOW.



    Thanks again!

The first thing you should check on a electric dryer when it does not heat or run is the voltage at the cord.

If you do not have the correct voltage your dryer will not heat and may not even start.

The dryer needs 240 volts for the heater to work. It gets 240 volts by using two 120 volt lines. If one of these 120 volt lines is dead it will not heat. It may or may not still run as the dryer only needs 120 volts for the motor to run.

If you have one 120 volt line missing power and it is the same 120 volt line that runs to the motor then the dryer will not run or heat.

How to check the ignition module


A mechanic would do a pin test for voltage.
You would need a VOM meter and a book with the specs.

The drum spins, but there is no heat.problem with dryer.


<li>Fuse could be bad -- Check the fuse for a break inside. If it's bad, replace it with an identical fuse.Temperature switch could be bad -- Use VOM to check the switch. Set VOM to RX1, remove leads and touch the probes to the switch's terminals. The reading should be zero or infinity. Turn the switch, and the reading should change from zero to infinity or infinity to zero. If not, the switch is bad.Thermostat could be bad -- Set the VOM to RX1, take a lead off one of the two outside terminals and press the probes to the two outside terminals. There should be a reading of zero. If not, it's badHeating coils may be bad -- Set the VOM to RX1 and remove the leads from the coil. Press the probes to the terminals.

Dryer won't work, keep blowing high limit fuse. I have cleaned out all of the blower and vent line and there is no obstructions. high limit thermostat test ok. any help


  • Power could be off- - Check the voltage at the outlet with the VOM.
  • Timer or thermostat could be bad -- Follow same tests as listed above.
  • Terminal block could be bad -- Use the VOM to check for voltage at the terminal block. Be very careful here, as the power needs to be on for this test. If you don't feel comfortable, call an experienced electrician.
  • Start switch could be bad -- Set the VOM to RX1 and remove one of the leads to the switch. Clip the probes to the switch's terminals. The reading should be infinity. Press the start button and the reading should change to zero. If not, the start switch is bad.

  • These, of course, are not everything that can go wrong with your dryer, but only the most common problems. When removing parts for replacement, I find keeping a notebook nearby to take notes on which wire goes where, to be a valuable assistant. Of course, when you take your faulty part to the appliance parts shop, make sure to have the make and model number for your dryer, just in case they need it. With that said, good luck and hopefully your dryer will be sound for a few more years.

    How do you make sure that the full 220 are going to the dryer? Is it possible that there used to be 220, but now are only 110?


    First get an VOM, if you don't know what this is have someone that does help you, and check the voltage at the outlet. Then go to http://fisherpaykelparts.net/techhelp/fisher-paykel-top-load-dryers-us-models/ This forum will work you through your problem.

    No heat


    Check the heating element for continuity (unplugged); and if OK (though can be OK until main current goes through and then becomes dis-continuous--so not foolproof), then if safe access could check with VOM (or grossly fluorescent/glow type voltage detector), that 220 volts was present at the heating element. If no voltage to element, then likely in the control system/timer and a different story.

    Crosley CEDS774JQ0 electric dryer. It wasn't drying well so I pulled the vent line and cleaned it out well, ran the brush down the filter area too. Good venting now. But no heat, none at all. Ideas?


    Do not know the model in particular, but by "not drying well" you mean not much heat, and then after cleaning there was no heat---would suspect the heating element (220Volts divides to 110 to make lower heat, like on a range burner) or operating on only 110v. The jostling could have completed the burn-out point of the heating element. Could check for continuity of the element (unplugged) using VOM (volt ohm) meter or flashlight bulb, wire, and battery--bulb metal to one end and wire to bulb tip and other end of wire to other end of element. If careful and safe access could check that voltage to heating unit is in fact 220 volts with VOM set to AC 600v setting (greater than 220v) unless automatic range setting VOM. (or check voltage to element first).
    Also, remember when finished to check that vent hose is to inner vent pipe, not just to cabinet; lint build up in cabinet is a common reason for heating elements to burn out.

    Dryer wont start


    Unplug the dryer and remove the rear panel.You will see a fuse in the exhaust vent 1 and 1/2 inches long by 1/2 inch wide and white in color.
    Check it with a VOM.(volt meter) If it is open replace it. Any appliance parts store has them.
    You can carefully jump the 2 wires together and start the dryer to verify the fuse if you do not have a VOM.

    Dryer will not dry clothes properly


    A - Things that could stop a electric dryer from heating:
    - house fuse or breaker ( needs two of them ), heating element, burnt wire, thermostat(s), thermal fuse ( not all models ), motor heat switch, timer, selector switch, burnt power cord/plug.
    A ohm meter test for these parts is here.


     Pull the dryer out away from the wall. Unhook the vent from the dryer completely. Do not put anything over the dryer exhaust on the back of the dryer. Do a normal load with the vent unhooked. If it dries better or ok like this then the problem is in the dryer venting. Like a blocked vent pipe or a smashed or restricted vent hose.
    A2 - If the vent  doesn't make a difference, then check the blower wheel for excessive lint build up, check that there isn't anything stuck to the air intake baffle inside the drum, (i.e. the screen on the back wall of the dryer when looking into the drum). Check the lint filter chute for blockage. Check that the heating element isn't shorted to ground. Check the exhaust temperature of the dryer. A meat or pocket  thermometer can be used for this. It should cycle between 120 degrees and 170 degrees. Check that the drum seals to make sure the are not worn out.

    You will need a volt Volt-Ohm (VOM) reader to fix this problem.
    This doesn't rquire sound technical knowledge for this but you should be good at following some instructions.
    This could be the effect of a number of problems. Here's a list of things to check and details on how to do it.
    • Fuse could be bad -- Check the fuse for a break inside. If it’s bad, replace it with an identical fuse.
    • Temperature switch could be bad -- Use VOM to check the switch. Set VOM to RX1, remove leads and touch the probes to the switch's terminals. The reading should be zero or infinity. Turn the switch, and the reading should change from zero to infinity or infinity to zero. If not, the switch is bad.
    • Thermostat could be bad -- Set the VOM to RX1, take a lead off one of the two outside terminals and press the probes to the two outside terminals. There should be a reading of zero. If not, it's bad.
    • Heating coils may be bad -- Set the VOM to RX1 and remove the leads from the coil. Press the probes to the terminals. If the reading is zero, the coil is bad.
    • Timer could be bad -- Disconnect the leads from the motor. Set the VOM to RX100. Clip the probes onto the leads. If the reading is infinity, the timer motor is bad.
