The thermal fuse is actually not part of the heating circuit but rather part of the motor circuit. The heating circuit is composed of the heating element, thermal cut-off, high-limit thermostat, timer, centrifugal (motor) switch, and the cycling thermostat depending on the model number of your dryer. All of these components are wired in series and failure in any of them results in the dryer not heating. Check for 240 VAC from the power outlet before proceeding with the troubleshooting.

Check the continuity of these components except the centrifugal (motor) switch which activates only when the motor is running. The cycling thermostat, if there's any, is located on the blower housing just on the right side of the thermal fuse. If your dryer has the thermistor instead of the cycling thermostat, no need to check it since it is not a part of the heating circuit.

The high-limit thermostat and the thermal cut-off are located on the heater housing. You simply bypass them including the cycling thermostat, if you don't have a volt-ohmmeter, by taping the wires together or jumping a wire between the terminals.

Check the continuity of the timer by turning it to any heat setting then check the continuity between each of the plug prongs and any of the thermostats or thermal cut-off terminals. You should get continuity with one of the plug prongs if the timer is good.

You can deduce that the problem is with the centrifugal (motor) switch if 240 VAC is present, the timer is good, and the thermostats and the thermal cut-off have continuity or bypassed but the dryer still doesn't heat up.

Please indicate the exact model number of the dryer for more specific troubleshooting advice or if you need further assistance. You don't have to accept or reject and rate this post to add information or post comments and follow-up questions. But accepting the solution will not stop you from communicating with the expert. You may continue communicating with the expert as long as you need assistance regarding the issue stated herein.

My electric inglis dryer has no heat at all


Check fuse/breakers for tripped breaker or blown fuse. if ok, than unplug drier, remove back and check power connectors to cable, if ok check element connections for burning etc.. if ok remove one connector and check for continuity from element terminal to terminal. if ok than check thermal switches for continuity, if ok.. possible defective timer or inertia switch on motor, or belt tensioner switch..

Electric dryer will not heat?


If the electric dryer does not heat at all then there are some possibilities that have to be checked to confirm the fault.
1)check whether you are getting power to the dryer from electric out let to which the dryer is connected. The power problem can also occur if the fuse is blown or the circuit breaker is got tripped.
2) Other possibility for dryer not heating is the blown thermal fuse. The thermal fuse is located to the exhaust duct inside the back cover panel. This fuse blows out if the dryer gets overheated or any short circuit occurs in the house when dryer is in working.
3) The other possibility if the power is ok and if the thermal fuse is ok. Then the problem can be due to fault in the heating element. The heating element looks like a long coil of special wire. You can check heating elements continuity with an ohm meter. If there is no continuity that means the element is bad and you need to replace it. The heating elements cannot be repaired it should be replaced if faulty.
4) But if all the above mentioned possibilities checks out OK, and still the same problem, then there is a fault in the wiring. Check the main power cord of the dryer which you connect in the electric out let. If the power wire is got internally burned out or got cut in between the dryer will not get proper power and will not work Due to partial power.
This will help. Thanks.

Hello there and welcome to fixya
Heating element Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable. To determine if the heating element is burned out, watch the part testing video at the bottom of this page. Thermal fuse On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.) To determine if the thermal fuse has blown out, watch the part testing video at the bottom of this page.

To determine if the heating element is burned out, you will need to test it for continuity it should read 000 on the meter if good and a 001 or a 1 means bad ok the meter needs to be set at the lowest ohms scale .

No heat


Hi.

If it is turning but not heating, check the thermal fuse if present. The fuse is also tested checking continuity. If the fuse is OK, check the thermostats in the heater assembly. If the thermostats are good, they will read zero or very low impedance at room temp.Depending on the model there are two or three thermostat/thermistors in the appliance.
If even thermostats are OK, check heating element. It must have continuity.
If element is OK, check wiring, then fan, then go for the timer control.

Here all parts.

Regards.

Ginko.

Dryer drum works but does not heat. Everything else works. I have checked the fuse and I have made sure it is not on air dry.


THERMAL FUSES MAY BE THE CAUSE OF THIS In recent years the makers of dryers are using thermal fuses to let you know something is wrong with your dryer. They are generally non resetting and have to be replaced. The thermal fuses are located on the heater element housing and should read continuity if read with an ohm meter. Most blown thermal fuses are the result of vent/air flow problems or a grounded heating element. Follow the diagram below to see how to check the continuity of the switch, and look closely at the switch to see a fairly close idea of what you are looking for, ok

OR it could be a thermostat.
Cycle and safety thermostats-read them with an ohm meter. Should show continuity .

or lastly, it might be
the Heat elements-Test heater element with an ohm meter. You will read continuity across a good element ( 8-12 ohms is an average element ).

IF you do not have an OHM-METER, then you can check these issues by following the directions below:

To check the thermal fuse - You can bypass the thermal fuse (just connect the 2 wires together) for testing purposes only.

To check the thermal cut-out - You can bypass the thermal cut-out (just connect the 2 wires together) for testing purposes only.


To check the thermostats for continuity - - You can bypass the thermostat (just connect the 2 wires together) for testing purposes only.

To check the Element: Try removing element and physically looking at the element wire for a break in the wire.

Kitchenaid superba dryer won't heat Where is the heater fuse located?


Q - My electric dryer runs but will not heat, what could stop my dryer from heating?
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.
Q - My gas dryer will not heat, what could stop my dryer from heating?
A - Things that could stop a gas dryer from heating:
- glow bar igniter, thermal fuse ( not all models ), coils on the gas valve, gas valve, thermostats,motor heat switch, timer, selector switch, sensor.
A page for checking gas dryers is here.
Meter testing and usage tips.
1. Power supply-check power supply at terminal block where cord enters the dryer. Should read 240V. If you read 240V here, tested with a volt meter, unplug dryer and test components with ohm meter.
2. Thermostats-Cycle and safety thermostats-read them with an ohm meter. Should show continuity . How common thermostats work.
3.Timer-The timer has a set of contacts that pass voltage to the heaters. If you can not determine by wiring picture what they are, check across the two terminals with the largest wires on them. The heater wires are almost twice as large as the others. You should read continuity with timer in heat mode.
4. Thermal fuses-In recent years the makers of dryers are using thermal fuses to let you know something is wrong with your dryer. They are generally non resetting and have to be replaced. The thermal fuses are located on the heater element housing and should read continuity if read with an ohm meter. Most blown thermal fuses are the result of vent/air flow problems or a grounded heating element.
5. Selector Switches-Read the wiring picture and determine which switch is closed. You should read continuity across closed switches.
6. Safety Switch on Motor-There is a safety switch on motor to insure that heaters can not come on unless motor is running. It is normally open when the motor is idle/not running, and closes when motor runs. In order to check with an ohm meter, remove the two large wires on motor switch and make them electrically safe. Tape them. Plug the dryer in and start motor. Check continuity across the terminals on the motor switch you removed the heavy wires from. If it is ok you should read continuity. Remember that the smaller wires in a dryer carry the 120V and the large wires carry 240V. There is no voltage on these two terminals with wires removed. It is ok to test with ohm meter.
7. Heat elements-Test heater element with an ohm meter. You will read continuityacross a good element ( 8-12 ohms is an average element ).
But darn it, I don't have a Ohm Meter....
To check the thermal fuse  - You can bypass the thermal fuse (just connect the 2 wires together) for testing purposes only.To check the thermal cut-out  - You can bypass the thermal cut-out (just connect the 2 wires together) for testing purposes only.
