How To Fix Dryer With No Heat ' Dryer Repair - PartSelect

Hi there,

Well if it's a gas dryer and if your dryer tumbles, but there is no heat then you may please check out the following -
1. First of all you can check out for proper air flow - Check the vent for proper air flow by placing your hand over the exterior vent while the dryer is running. You should feel a strong flow of air. If not then check the lint trap. It is located either on top of the dryer or possibly just inside the door. Remove any lint that has built up in the lint trap. Cleaning the lint trap should be done regularly, even as often as after every load. Do not operate the dryer without a lint trap in place.
2. Secondly you can check out the Ignitor - gas dryer blows air through a burner assembly to heat the air. The burner assembly consists essentially of a gas valve, ignitor and a flame sensor. If any part of the burner assembly malfunctions, the result will be low or no heat and slow drying of the clothes. Post comments for further help or information.....

Good Luck!!
Thanks for using FixYa!!

You must never attempt to repair or troubleshoot your home-appliances unless the electrical power is switched off and the plug removed.

Unplug or electrically isolate the appliance before checking any part of the wiring, or opening the protective covers
Kenmore dryer troubleshooting - The dryer will not operate
1. Check that the power is on to the machine. The power indicator light will if this is the case.
2. Check that the door is properly closed. When a door interlock switch is not activated properly the machine will not start. The best check is to open and close the door several times and sometimes the microswitch may be sticking and some do come loose due to vibration
3. The dryer start switch hasn't been pressed or turned properly.
4. The dryer program hasn't been selected
Kenmore dryer troubleshooting - Dryer does not heat
1. The electrical circuit fuses or circuit breakers have tripped. If they blow a second time then you may a faulty or blown heating element.
2. Heating element thermostat is faulty.
3. Heating elements are faulty. In rare cases the wire connections may have burnt off the element. WARNING Do not open the rear access of the dryer until the dryer is unplugged!
4. Heating overheat cut-out switch has tripped out or is faulty. Some machines also have a replaceable thermal fuse that should be checked.
Save time with easy cleaning - burners are sealed so there are no cracks or crevices to trap debris. Cook top spills wipe-up quick and easy. Plus,

This is usually the dryer coils have failed. They tend to fail as they heat up. They are inexpensive and easy to replace. Here is a video on replacing the dryer coils.

The thermocouple may be going bad. The thermocouple is what "tells" the control unit that there is a flame. If it doesn't send it's signal, the control thinks the flame went out and shuts off the gas to prevent an explosion.

Try vacuuming lint and dust out of the burner intake and exhaust ports. Hope this helps!

I find that quite often the ignitor is out of alignment or the glass window is covered with lint.

There are two common styles of ignitors, glow ignitors and spark ignitors. The ignitor ignites the gas either by heating up and glowing, or by sparking. If the ignitor fails, the dryer will not heat.

The easiest way to check the ignitor is to observe it. Remove the small access panel in front, select a high temperature setting and start the dryer. Watch the burner assembly, shortly after starting the dryer the ignitor should begin to glow or spark. If you see it glow or spark, then the ignitor is working.

How are ya?

The heating element is supposed to cycle on and off to maintain a set temperature. If it takes too long to come back on again, then the thermistat is malfunctioning.

Take a temperature probe and stick it in the drum and let it run for a few minutes and note the temperature. Should be consistantly near 90 - 130 degrees. Good luck :)

There is a hub and bearing that needs to be replaced you will need to have this serviced by a qualified tech. The whole front of the dryer has to come off and the basket needs to be removed.
