Most common problem on this unit is the blower motor. It needs replaced not the control board.

Continues to blow the high temp stat. I clean the blower and replaced the venting. I also replaced the heating coil the dryer heats up for a load and then it stopss heating. I test the high temp stat


DRYER OVERHEATING:

Heating Element
A defective heating element can make a dryer too hot. If the element partially shorts out, it can produce heat all the time, regardless of whether the dryer is calling for heat. Remove the heating element to inspect it. The coils should not be touching each other or anything else.

Other Causes and Conditions
Air Flow Problem
Dryers need good ventilation to work properly. If the vent is clogged it can make the dryer too hot. Clean all of the vent tubing thoroughly.

Cycling Thermostat
Although not common, a defective cycling thermostat can make the dryer too hot. The cycling thermostat is supposed to turn on and off the heat to maintain the proper temperature. If the thermostat is defective it may keep the heat on too long. The thermostat is not adjustable or repairable, it must be replaced.

Felt Seal
Most dryers have a felt seal at the front and rear of the drum to keep the heat inside the drum. If the felt seal is worn away or missing, the dryer may keep heating and make the dryer too hot. This is not common.

Blower Wheel
A defective blower wheel will not spin properly and will not vent the hot air, making the dryer too hot. Check to see if there is adequate airflow out of the dryer.

Frigidaire affinity dryer wont heat


Hello - Do you have a gas dryer? If so, and it only heats up sometimes but provides a gas odor, it could possibly be a defective gas supply or igniter. Try resetting the unit by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes and turn on the fuse for the dryer. Turn on the dryer and select a normal cycle. If it proves to be ineffective, I suggest contacting a professional to move forward accurately. Since it is such a complex unit, the technician will likely diagnose to confirm if it has a defective sensor, control board or high limit thermostat.

If you have an electric dryer, the issue may lie with the main control board. However, if the unit is not producing any heat please have a professional diagnose the heating element and the blower assembly as well. Either, or, could be faulty at this time. This is not a typical DIY job so please consult a professional.

Hotpoint ultima cd80 condenser dryer has stopped heating can it be repaired/reset or is it a new unit and how much? Cheers


Hi

Thanks for using FixYa. If your dryer isn't working or isn't getting heated up, you'll need to check the following to be sure what exactly the issue is--
Blows fuses or trips circuit breaker —ELECTRIC Models:
• The amperage readings are at 240 volts. One line will be 24 amps and the other line will be 21 amps. The neutral line will be at 3 amps. If the above amperages are not present, then the house wiring, fuse box or circuit breaker should be suspect.
• Shorted heating element to housing.
• Incorrect wiring or a wire shorting to ground.
• Drive motor winding shorting to ground.

Blows fuses or trips circuit breaker —GAS Models:
• If igniter is not glowing, check for 120 V at igniter.
• Igniter harness may be loose and shorted to base.
• Incorrect wiring or a wire shorted to ground.
• Drive motor winding shorting to ground.


If it runs for a few minutes and then stops, then check for the following:--
• Empty dryer.
• Check motor spins freely.
• Lint buildup around drive motor.
• Low voltage present.
• Blower impeller blocked in blower housing.
• Drive motor - start switch contacts stuck closed.


Please do rate the solution and revert for further assistance.


Thanks

Whirlpool lgr7648pq0 gas dryer no longer heating; just blowing air; no exhaust issues;


More than likely you have a burned up heating element. There is a remote possibility that you have a blown circuit breaker or fuse in your house. The blower is wired for and only requires 120 volts but the heater element requires 220 volt service. Usually there are two circuit breakers in your house breaker or fuse panel that provide power for the dryer. One of them may be tripped/blown and the other one may be ok..still on...and providing power to the blower. So...check to make sure there is not a blown fuse or circuit breaker tripped. This is the easy solution if it applies but probably the heating element is bad and will need replacing.

My whirl pool dryer has to be turned on bout 3 to 4 times


Ok, check the exhaust hose for obstructions. make sure the blower assembly is not clogged and, the hose is clear of any debris. the exhaust hose should blow out hot air forcefully. if the force of the air isn't blowing hard, it will not create a suitable drying environment for the element. this poor ventilation will also damage the heating element or burner Assembly.

Now, if there is sufficient air flow out of the exhaust hose, this will confirm control failure. replace the dryness sensor and control board in this case.

Here's a quick way to test for clogs. take the hose of the backside of the dryer then, start the cycle. if the drum sorts to become hot after a few minutes with the exhaust hose removed form the back of the unit, this will confirm a major block in the hose or blower assembly.

Dryer blows house fuse --keeps tumbling--no heat


If the dryer turns on, drum spins, but you have no heat, any of the following components could be bad:

Heating Element
Thermal Cut-Out
Hi-Limit Thermostat

All these components COMBINED, should cost less than $100. If you fix it yourself, you will avoid the additional cost for labor.


If the dryer isn't blowing ANY air at all, but the drum still turns, you may have a bad blower fan assembly inside the dryer. Or, the blower fan assembly may be clogged.

Now, if your dryer performance has been failing (i.e., clothes taking longer to dry), it may be for a reason. You need to ask yourself when the last time you cleaned the dryer ventilation. If you can't remember, or if it has never been done, this can contribute to the dryer failing. All dryers need proper air flow in order to dry properly. If the ducting becomes clogged, the heating circuits will actually overheat and eventually fail. This usually results in the Thermal Cut-Out (TCO) blowing or the Heating Element failing or BOTH. When these components fail, they must be replaced. Remove the dryer hose from the back of the dryer and inspect it thoroughly from where it leaves the dryer to where it exits your home. It should be clear with no kinks or clogs. If your vent line runs under a crawl space make sure it is suspended above the ground and has no sags where lint could collect. RULE OF THUMB: The SHORTER and STRAIGHTER the vent duct, the BETTER. After you inspect the vent ducting, turn the dryer on and make sure you have forceful air flow coming form the dryer. This will prove that your blower fan is working properly or not. Since you stated that your dryer is not currently heating, the air will be cold, but you should still have some force behind it. If the air flow is weak, you need to clean the duct work INSIDE the dryer. It is important to keep a dryer checked routinely. I recommend once per season (that's 4 times per year). Dryers are the cause of many house fires. These fires are due to lint accumulations inside the unit catching on fire. A little preventive maintenance can prevent significant problems in the future.
Getting to the heating circuit to determine if the components are good or bad is the next step. If your dryer has the lint screen on the top of the unit, you will need to remove the back panel of the dryer to expose the heating circuits. If the dryer has the lint screen in the door, you will need to remove the lower kick panel under the door by using a putty knife to release the retaining clips. They will be located along the seam in the front about 2 inches in from each side. You have to remove the entire front panel on some models. This is accomplished by lifting the dryer top and removing the screws that hold the front panel in place.

NOTE: The heating circuit should be troubleshot with the dryer UNPLUGGED. Dangerous voltages are still present with the dryer turned off. Resistance readings are as follows:

Heating Element (located inside heater box) – remove the two RED leads from the ceramic terminals on the heating element and take a reading across the terminal points. It should read 9 - 13 ohms.

Thermal Cut-Out (TCO) (mounted to the heater box.) - unplug wires and take reading across connector tabs. Reading should be 0 ohms.

Hi-Limit Thermostat (mounted to the heater box, closest to the heating element leads) - unplug wires and take reading across connector tabs. Reading should be 0 ohms.

If any of the above readings are abnormal, replace the component. NOTE: If the TCO or Hi-Limit Thermostat is defective it is highly recommended by most manufacturers to replace BOTH components at the same time. They are often sold as a set.
