The following link explains how to troubleshoot an electric dryer with a no heat problem:

http://www.fixya.com/support/r630242-dryer_runs_but_not_heat

First, begin by unplugging the dryer and verifying the voltage at the wall receptacle. You should read 220-240VAC across the two Hot terminals (left and right slots). If the voltage is incorrect, check to make sure you don't have a breaker tripped. Some homes use 2 separate 120VAC breakers to provide power to the receptacle vice using one 240VAC breaker.

If the voltage IS correct, leave the dryer unplugged and remove the cover plate on the terminal block in the back of the dryer (this is where the power cord is installed). Plug the dryer back in and take a voltage reading across the two hot (RED and BLACK) wires at the terminal block. You should read 220-240VAC. If the voltage is good, you have an internal heating problem. If the voltage is bad at the terminal block, but good at the receptacle, you have a bad power cord.

The reason a dryer will still run if the input voltage is incorrect, is because the drive motor only uses a portion of the 220 service. The motor runs off 110-120VAC, while the heating circuits require 220-240VAC. So, if you are missing 1/2 your input voltage due to a tripped breaker or bad power cord, your dryer will exhibit these symptoms.

If you determine the problem to be internal, the heating circuits will either be located in the rear of the washer on the right hand, or under the dryer drum on the right hand side. Usually, an easy way to determine is by the location of the lint screen filter. If the filter is on top of the dryer, the heating circuits are in the back of the dryer. If the lint screen is in the door, the heating circuits are located under the dryer drum.

All dryers are not constructed the same. However, generally, the Heating Element is located inside the heater box. The Thermal Cut-Out (TCO) will be located on the outside of the heater box on the end opposite the heating element terminals. The Hi-Limit Thermostat will be located adjacent to the heating element terminals. If either the TCO or Hi-Limit Thermostat are determined to be bad, replace both components at the same time. That is why these components are commonly sold as a set. Failure to do so may result in premature failure of any parts you replace. All these parts can be found at appliancepartspros.com, searspartsdirect.com, pcappliancerepair.com, or repairclinic.com. The average cost of these components varies, so shop around for the best price.

If you have any questions, please let me know. I hope you find this information helpful.

Amana 7300 tandem dryer not drying. the drum rotates but no heat. can this be fixed by me?


GOD IS STILL GOOD !!!!

ELECTRIC Dryer no heat or little heat, or shuts down to fast:

Check your venting and lint basket. Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity OHMS CLOSED CIRCUIT. If not its defective or has a short if its grounding out? Which in turns causes blown fuses or thermostats or overheating.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle. Which are reflected by the thermostats.

Test the wirings to control panel and the switch.
Try also a different outlet, and eventually check with a tester the power cord.
Also the switch must be tested.
If the wirings are ok then the whole control panel can be replaced.


If you want to buy parts you find them here.

3-5 ACCESS TO THE BLOWER WHEEL OR THERMOSTATS

To get to the blower wheel, remove the back of the dryer.

The blower wheel is under the bottom of the lint screen duct to your left, as you look at the back of the dryer.

The operating thermostats are at the blower wheel outlet.

In electric models, the hi-temperature cutout thermostat is mounted to the heat riser.

3-6 TEMPERATURE CONTROLS AND HI-TEMP SAFETIES

These clothes dryer machines use operating thermostats to control the temperature inside the drum, and hi-limit thermostats to prevent overheating of the dryer drum.. Many machines also have extra temperature controls, such as bias thermostats and heaters, hi-temperature cutoffs, and thermal fuses.

Bias thermostats are just like regular operating thermostats, except that they are mounted inside a bias heater. When the bias heater is energized, it generates a small amount of heat, which causes the operating thermostat to open sooner, keeping the dryer drum cooler inside. Thus a bias heater allows a single operating thermostat to act like both a hi-temp and a lo-temp operating thermostat.

A thermal fuse is found on the blower outlet, right next to the operating thermostat(s.) This fuse will blow when too high a temperature is sensed at the outlet; usually when one of the operating thermostats has failed. If it blows, the motor may not start, or you may get no heat (no voltage to the burner.)

A thermal cut-off is mounted on the clothes dryer heater box. It is a back-up for the hi-limit thermostat. Whenever you replace it, you should replace the hi-limit thermostat, too. A high-temperature condition causes it to open, an overheated grounded heat element may also cause it to open.

Dryer not heating up


ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks.
If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the
wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed
component. The switch is inside the dryer main housing near the door frame.
Sometimes you need to raise or open the top or front of the dryer to reach the switch.
Check for continuity you should have none with door open, and should have a reading when closed.
If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or the dryer,as this condition can cause
heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the
thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor one at a time by removing the two wires and taping them together with electrical tape
or with an ohm meter to test the thermostat/thermistor. (Should have/show continuity)
If the coil heats up then replace the thermostat/thermistor.
(Thermal fuse.If it overheats the dryer will not operate. It's located on the blower housing. It cannot be reset. A vent clogged
with lint can cause it to overheat. You can test it with an Ohm meter or continuity checker, if no continuity, replace it)
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST.
This could cause a FIRE, as you have removed the safety of overheat from the machine.
Right after replacing a dryer element, always run the dryer on 'air fluff' / 'no heat', and go outside to verify there's
plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

Maytag dryer won't rotate after blower wheel replacement


Check the drive belt and belt tensioner. From the way you describe it, the belt is loose and with a load in the drum, it will not rotate due to belt slipping.

Whirlpool dryer will not spin


Since your dryer is "new" it is under warranty. I will explain the possible reasons why it will not spin. Then you can decide whether to make the warranty call or not.

If your dryer doesn't tumble, check these:

Belt
Motor
Door switch
Belt Dryers have a drive belt that turns the clothes drum. If the belt breaks, the drum stops rotating. Then you need to replace the belt, and often the idler pulley, because the pulley tends to wear out at the same time.

Click here for a belt installation diagram.

Motor If the dryer motor only hums when you press the Start button, the motor may be burned out. Here's how to test the dryer motor:

  • Remove the belt.

  • Check for obstructions in the blower fan housing.

  • Manually rotate the shaft of the motor.

If the motor is very stiff, or impossible to rotate manually, and the blower fan housing is clear, you need to replace the motor.

If the motor rotates freely, run the motor momentarily with the belt removed and the blower in place. If the motor runs fine with the belt removed, there may be a problem with the idler pulley or the clothes drum. Try to rotate the drum by hand. If it is very difficult to move, correct any problem with the rollers or pulley, and then reassemble the dryer and try it again.

If the motor hums but doesn't rotate on its own even with the belt removed--yet you can turn it freely by hand--you usually need to replace the motor or the motor start capacitor.

Door switch Your dryer can't operate at all if the door switch is defective. It's inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. If it's defective, you need to replace it.

Kenmore dryer does not heat up. Mod#110 60912990


First I would make sure that you have 240volts coming into the dryer. Then I would check the thermal cut-off in is a fuse on the housing of the element. that should be it but if not look for the heater relay.

Drum drive/motor growling, also very brief repeated hesitation audible


Dale you are correct, the dryer has a part starting to fail. If you remove the top and shift the cabinet the noise may increase or decrease. If this happens, then the rear panel is bent in that supports the rear bushing. You can replace that to resolve this. If the noise doesn't change, I suggest you check the blower, Sometimes the blower will spin freely on the motor shaft and cause a noise. Since this blower wheel also cools the motor, it could be spinning. Try removing the blower and add a washer behind it to tighten it to the motor shaft. This is just a press fit blower wheel. If that doesn't resolve the issue, then replace the blower wheel. Hope this helps.
