Question about Whirlpool Dryers

1 Answer

Hello, I have whirlpool dryer model # LER7646JQ0. My dryer works great with one exception, it has no heat. I checked the heating element and all of the coils are intact. I then replaced the thermostat and thermal fuse (both located on the dryer vent) and still NO HEAT. I was then looking into replacing the thermal cut-off and the hi limit thermostat (part # AP3094244) but the image looks different from what is on my unit. The hi limit thermostat on my unit has three wires connected to it. What can I do to fix this issue?

    Hello Mr. Markus. My apologies for the doubled message. I have a digital multi-meter. My electrical outlet reads 243vac. On the washer, one wire read 120vac and the other reads 121vac.

    Hello Markus
    My apologies for the doubled message. To answer you, yes I have a digital multimeter. The electrical outlet reads 243 vac. On the back of the dryer, one of the wires reads 120 vac and the other reads 121 vac.
    Thanks again for all your help

    I really appreciate all your help Mr. Markus. How exactly do I check each component and what are they supposed to read?

Hello avonladywend,


After reading your post I can't help but wonder, have you checked to insure the dryer has 240vac going to it. These dryer's will appear to work almost perfectly with 120vac, with one exception...you guessed it, No Heat !

If you know the location of your homes service panel go to it. Locate the 30amp breaker and turn it all the way "off" and then all the way "on" do not just identify it and assume it is ok because ot doesn't appear "tripped".

This happens all to often when I go to a customers home. The first words out of there mouths is "It's not the breaker I checked" and then I physically check "reset" the breaker ( after verifying the dryer is only receiving 120vac and not 240vac with my meter ) and what do you know, heat !

That could be the problem all it's own. The other thing to look for is a poor connection ( loose and burnt or badly oxidized...or both ) on either of the "hot" cord lines coming into the unit, either the red or black.

Let me know what you find out, but that's where I'd be looking before installing anymore part's.

good luck.

    Hello again,

    So having checked the breaker and confirming it is ok as well as the wires appearing fine, is it safe to conclude you have a voltage meter or multimeter of some type ? If so, is this the method you used to check the heating element and thermostats, for 240vac at the dryer ? Let me know before moving forward so we avoid going in circles. There are other factors which can interupt the heater getting 240vac, but it will require a metering device.

    I'll watch for your reply, Thanks.

    Hi,

    as I stated in my last response to your reply "whats next" I need to know if you have a multimeter or some type of measuring device to check ohm values, voltages etc. If you don't you'll either need to buy one, call in a pro or continue to guess at changing parts. Let me know and we can move forward, otherwise we can't help as affective as possible.

    Thank you.

Heating element not working on a ele ctric dryer


With the power disconnected you can check the resistance of the heating element. Remove the back of the dryer. Remove the connectors to the element and if the resistance measured is any greater than 25 Ohms then the element will need replacing. If the element is OK then check the thermal fuse(s) or thermistor on top of the housing which are there to present overheating. That’s really all there is to it if the motor is running and the timer id working OK.

Whirlpool Dryer not heating


The motor has to be running for voltage to exit the motor going to the heater. With the back off the dryer and the motor running you should read 220 volts at the heater if all safetys and thermostats are good.
There is a thermal cut out relay on the heat canister. It must read continuity also.
Remember you must remove at least one wire from each component being tested to get a true open or closed reading. If a wire is left connected you get a false reading.
The heating element could be broken and part of the heater wire touching the canister. This would cause a continuity reading and still no heat.
Finally, yes,the centrifugal switch in the motor could be bad and not sending power to the heater on the red wire.

Everything works but no heat


Double check that both the breakers in your electrical panel are ok. Dryers are 240 volts - one side of the circuit does everything except heat, the other side only does heat. Sounds like either a single breaker has flipped off, or you have a bad breaker.

Can I test dryer timer to see if its any good?


I do not think a "NO HEAT" problem can be caused by the timer.
Sounds like another electrical problem:
Have you check the house breaker or wall receptacle to see if you are feeding 220V to your dryer?
Have you check your hi-limit thermostat to see if it has continuity?

Those are the most common causes of "NO HEAT"

Dryer Stopped Heating


Use a multimeter to check the heating element. You can't always go by looks. Check continuity and if there is none, the element is defective. Another thing to check is the thermal fuse. It is about an inch long and is usually attached to the exhaust duct. Use the meter to check it as well and if defective, replace it. Sure hope this helped and best wishes.

Hello,
In all probability, you have either a blown thermal fuse ( non-resettable type) or an open heater element. Next post, please include the model so that I can provide more detailed information for you..
