99% of the time it is the element. You need to check the resistance of the element if ther eis none or very little than it is the element. Also you can check and make sure a/c is coming to the element when iti si on

Dryer overheating on timed dry/no heat settings


Replace the thermostat. A very inexpensive thermocouple that is not sensing the heat anymore and caused the element to overheat. In the UK the part will cost less than five pounds!
If the element had touched the ground, your safety earth leakage breaker in the fuse box would have tripped.

DRYER NOT HEATING UP


Matthew Campbell,
I understand that your Frigidaire electric dryer will run but is not heating up. What I would suggest would be to give the appliance a hard reset.
You can do this by either unplugging it or cutting the power at the Circuit Breaker for 3-5 minutes. After resetting it for the 3-5 minutes, bring power back to the dryer. Run any cycle and see if you are getting heat or not.
If you are not getting any heat to the appliance, it could be either something to do with the heating element or possibly the control board itself. The other possibility would be the wiring going between the heating element and the control board.
I would recommend contacting a local authorized technician to determine what exactly is the root of the dryer not heating.
-Best Regards-

My whirlpool dryer comes on and runs good but it wont get hot can you tell me whats the problem


Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.

Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.


Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.


Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

Whirlpool cabrio dryer not heating


Could be that tech left something disconnected when he was working on it. I had a similar situation with a gas house heater I called for service only because it was gas, the guy told me same thing he "thinks" it was the motherboard. I was skeptical to say the least so I found the service manual and found out it was a $40 relay which I then fixed myself.

As to your problem yes it could be the motherboard before that guy messed with it now it might be more than that. Most times when an electric dryer stops heating it is the heater coil that burns out. You can check that with a cheap ohmmeter it should read resistance and not be open or zero. Your heating coil is located under the back panel of your dryer.

Hi from retired Englishman in SW France,
I suspect that either the heating element is malfunctioning or the control board is. Sorry but either will mean an engineer's visit ;-0(

Does not heat up


usually when your duet dryer does not heat it could be one of a few things. First you need to make sure you have power going to the dryer you need at least 240 ac volts for the heating element to come on. If you have power going to the dryer take the bottom pannel off it has two screws holding it on and your heating element will be on the right below the drum you need to unplug the dryer and take the two wires off the heating element they will be red, use a multimeter and chech the ohms on the heating element you should have around twenty ohms if you have 20 ohms than go to the next step. there is a white thermal fuse behind the lent filter check the fuse to see if it is open or close with your ohm meter if it is closed replace control baord. control board is located on the top below the pannel.

Heating element


The model number you provided suggests that the lint screen is on top of the dryer, right? If so, the heating element can be accessed from behind the dryer by removing the rear panel. Of course, you should know this already since you stated you've already replaced the thermostat and fuse. The heating element is located on the right-hand side as you are looking at the dryer from the rear. There are TWO components on the heater housing. One is the high limit thermostat, one is a thermal cut-out. Are these the components you mentioned replacing? BOTH should read a short (0 ohms) when measuring resistance with the dryer turned off. If you haven't replaced both of them, double check to see if they are both good. The high limit thermostat will be located closest to the ceramic heater connection. The thermal cut-out will be mounted to the heater box. Perform a resistance check of the heating element as well. Measure across the leads of the heating element at the ceramic terminal connection. It should read between 8 - 13 ohms if good. If your readings prove that the heater is bad, it can be removed by using a 5/16" hex drive. The heating element should slide out the bottom of the heater box housing. Sometimes removing the heater box, and then removing the heating element is easier.

Your dryer is also equipped with an electronic cycle control board under the control panel that goes bad from time to time. This also may affect the dryer heating circuits. Inspect the small circuit board for any obvious signs of burned components.

I hope this information is helpful to you. If I'm wrong about your dryer configuration, please post back with comments, so I can give you proper instructions.

CAUTION: Make sure you UNPLUG the dryer prior to making any resistance checks. Dangerous voltages are still present with the dryer turned off.

PS I hope I'm not insulting your intelligence, here. As a rule, I tell everyone this information because some are not as savvy as others.
