Question about Roper Dryers

1 Answer

The heating element will not engage. I have tested the Thermal fuse, the High Limit Thermostat the upper teermostat and the element itself and all are positive. Am I missing a fuse? Is the probelm in the console controls?

Hello,
With power detached, remove wire feeds to heating element and remeasure it while it is isolated from other circuitry. If you don't do that, you may be measuring some continuity thru other components in parallel with the element. Get back to me if you don't have an open heater element.
Regards,
Rick

Dryer spns but there is no heat


probally the heeting element

Electric dryer spins no heat, replaced heater element and high limit thermostat, tested thermal fuse and it does have 0 ohms, thermistor reads ~50 ohms.


in addation to checking the high limit t-stat have you checked the thermal cut off (the small t-stat) on the heater housing where the element fits into, the high limit t-stat and the thermal cut off BOTH shoud have 0 ohms (the thermal fuse is in the blower housing) the cut off is on the heater box, if you have checked those to be good, check that the heat relay on the control board is closing and sending power to the element, if not replace the control, if all above are good then the motor switch is bad and not sending power to the element(thats a built in safety feature so the dry would never heat when the motor isnt running)the element of course heats only when 240 volts ac is to the element ,120vac from the relay on control through the high limit t-stat then through the thermal cut off finally to the element and 120vac from the motor switch for a comined 240 vac

No a kenmore 80 series dryer will not heat . if the heating elment is good & fuse is good what else could be the problem


The heating circuit is basically composed of the heating element, thermal cut-off, high-limit thermostat, cycling thermostat, and the motor centrifugal switch. The problem is very likely in the thermal cut-off and the high-limit thermostat located on the blower housing. The thermal cut-off blows when the high-limit thermostat fails and cuts power to the heating element. Both the thermal cut-off and the high-limit thermostat need to be replaced if the former is blown open. Click on the link below for the detailed instructions in troubleshooting this kind of problem.

Troubleshooting Whirlpool and Whirlpool-Made Electric Dryers Running But Not Heating

Where would the fuse be and how hard to get to, is it in the upper unit? From behind? or lower unit? Running but no heat.


The problem is obviously in the heating circuit which is basically composed of the heating element, thermal cut-off, high-limit thermostat, cycling thermostat, and the motor centrifugal switch. The most common part that causes the dryer not to heat is the thermal cut-off and/or the high-limit thermostat. Verify this condition by bypassing the said components.

Disconnect power then access the thermal cut-off (cut-out) and the high-limit thermostat. Disconnect the wires of each component then connect them together and insulate it properly. Reconnect power then start the dryer. The problem is indeed in the thermal cut-off (cut-out) and the high-limit thermostat if the dryer heats up. Replace both parts and it should solve the problem. It is an easy and cheap repair to make. Indicate the exact model number of the dryer should you need further assistance.

Also bypass the cycling thermostat if the dryer still doesn't heat with the thermal cut-off and the high-limit thermostat bypassed. Check the heating element visually for obvious broken or damaged coil. An ohmmeter will be of great help in checking the resistance/continuity of the heating element. Replace the heating element if broken or damaged, NEVER attempt to repair it.

The problem is likely in the motor centrifugal switch if the dryer still doesn't heat with good heating element and the three components above bypassed. Indicate the exact model number of the dryer should you need further assistance.

The high limit thermal switch on heater burns out.


There are two thermostats, a 'limit' or 'operating' thermostat which turns the heating element on and off, and a 'high limit' or 'safety' thermostat which oversees the 'operating' thermostat by opening and removing power to the heating element when the upper limit temperature is reached. Basically, the only difference between these two are the temperature ratings. The 'high limit' is higher than the 'operating' thermostat. The thermal fuse is the last resort protection.

First and foremost, you must know that every inch of your exhaust vent pipe is clean.

Usually, a bimetallic limit switch will degenerate in the direction of too low of a temperature range because as the parts wear out inside, the mechanical tolerance widens (the tiny rod that pushes the contacts together gets shorter).

The high limit thermostat is by the thermal fuse. The operating thermostat is in the blower housing.

Check the fan impeller for broken vanes and lint. The impeller is directly coupled to the motor and should not turn without the motor. The fan housing and ducting should be free of excess lint.

Good luck.

Just replaces heating element in GE dryer. Dried one load but does not work, now. Light works, so it has power. Suggestions?


I would check the thermal fuse or thermostat. If the thermal fuse is blown check for obstructions in your vent then replace. For a video on testing these components go to www.appliancehelponline.com/servicemanual.html scroll down to troubleshooting an electric dryer.

For Dryer Model LER7646EQ1, dryer runs but no heat, It could be the heating element, the thermal fuse or other. Also the dryer has been running hot.I do not know how to remove the front panel


This sounds like a faulty thermal fuse or heating element. The fact that you said the dryer has been running hot could indicate that the heating element was making contact with the heater box or the high limit thermostat is faulty. Both the thermal fuse and heating element can be tested using a multimeter or ohmmeter and checking for continuity. A lack of continuity means a faulty component. When necessary to replace a thermal fuse it is best to change the high limit thermostat as well. They will sometimes come as a set from a parts supplier. Really sorry for your trouble and I hope this helped. Best wishes.

My kenmore 70 series dryer is not heating up. At first it just took longer and longer to dry, but now it isn't drying at all. This happened after the dryer was moved in order for the washing machine to be...


Not funny at all, I suspect. It sounds like the problem originated due to a faulty high limit thermostat or a partially burnt heating element. I would replace the thermal fuse and the high limit thermostat. These two components can be purchased as a set. Also check the heating element. It can be tested using a multimeter or ohmmeter. Check for continuity. A lack of continuity indicates a bad component. The thermal fuse is normally attached to or near the exhaust duct and the high limit thermostat is attached to the internal ductwork. The thermal fuse can be tested in the same manner. I will attach a photo of a high limit thermostat and thermal fuse for reference. Sorry for your trouble and I hope this helped. Best wishes.

Dryer does not heat ellement is good


If the dryer won't heat and the heating element is good, then check the thermal fuse and the high limit thermostat. The thermal fuse is located just inside the rear of the dryer and is mounted on the exhaust duct. Test it for continuity using a multimeter. A lack of continuity indicates a blown thermal fuse. '
The high limit thermostat is a small round, black device mounted on a metal plate and attached to the internal ductwork with two screws. It can be tested for continuity. It should have none. If it has continuity it is faulty. I am attaching a photo of the thermal fuse and high limit thermostat for reference. Hope this helped and best wishes.

the thermal cut off wires do not matter how you put them on.. The high limit is wired in series with the heating element.one red thick wire to element the wh/red top side of the high limit stat out of the high limit sat(other side) then goes to the other side of the heating element
