My Kenmore dryer gets way too hot on the lowest setting. I have taken off the cover and can see the element glowing red hot on all settings. Is there a thermostat that controls the temperature or is it in the switch? George
Answer Hello George,
The temperature is controlled by the cycling thermostat. In case it fails, the high limit thermostat should prevent the heat from getting high enough to burn out the heating element. In case the high limit thermostat fails, the thermal cut-out should blow. With all of these safetys on the unit, it is a good bet that the heating element 3387747 may well be shorted to ground.
A couple of things to check. Use a volt/ohm meter part #TJMA-DM1 to assist you in your diagnostics. Measure the resistance of the heating element. Make sure the element is not shorted to the... more case one element terminal at a time. Remove the element and look at it between the windings to see if it has expanded and shorted. This will make it stay on during cool down. The 2nd device is the thermistor part #3387134. It should be open at cold temperatures. If the inner contacts have welded itself closed then it will not open. Providing constant voltage to the element. It is best to also change the safety thermostat part #279816 because it has been weakened as well.
I have checked the heater element for grounding and all looks good. Checked continuity and all seems to be ok. I have replaced thermal cut off fuse 2 times and keeps blowing them? No restiction in the vent tube.
Answer Hi. Are all the terminal block post nuts tight? Are all the wiring connections tight? Some where there is a condition allowing too much amperage draw. The thermal cut off kit part # 279769 blowing may be that after the element part # 4391960 has been heated for awhile it gets "lazy" - expanding and barely touching one side of the element casing allowing the direct short to happen. Is the blower wheel part # 694089 rumbling loose on the motor shaft and cannot move air as efficiently through the system? Thank You.
My Kenmore Elite electric dryer (MOD: 110.62084101) keeps blowing the thermal fuse. I have cleaned the ducts (the airflow is great) and replaced both the fuse and the thermostat, but the fuse seems to last only about 30 days. The heater coil is NOT grounded and the thermostat is NOT faulty. I tested the thermostat by checking the continuity with the multimeter while holding an open flame from a lighter on the thermostat; it opens the circuit when it’s heated and closes the circuit when it cools off, like it’s supposed to. I have already replaced two sets of fuses and thermostats and both times the thermostat was working, so I’m pretty sure that the temperature near the fuse is not equal to the temperature near the thermostat; I don’t know why. I’m running out of ideas. I’m considering hammering the heater housing duct where the thermostat is attached, so the the thermostat is deeper into the heater housing duct, which will hopefully allow it to get hot enough and open the circuit before the fuse blows. Any suggestions? Thanks.
Answer Ivan, We'll need to start in a nother direction. First, check the blower wheel, make sure it's not loose on the shaft, cracked, brokrn or the vanes aren't clogged. Check and make sure the tumbler seals and the blower seal fit tight against the drum, and blower housing. You may have to use an amp probe meter and check the amperage draw on the heater circuit (20 amps +/- 10%) and should have a resistance of 8.5 to 11.5 ohms. You also want to check to see if there's an amp draw, when the dryer is not running, that would indicate a faulty heat circuit in the motor switch or heater relay. Aws a last resort, you may want to check the wiring and repalce the thermistor 8577274 there is a possibility there.
trying to replace thermostat in dryer, unable to get back off even with all the hardware out?
Answer Swant50, Your heater and fuse kit are accessed through the front of the dryer, not the back. Unhook and remove the front lower access panel, you see the heater assembly 3392537 mounted to the right side of the dryer base assembly , and the thermal fuse kit 279769 mounted to it . Make sure you unplug the power cord, or turn power off to the dryer, before you start anything.
My Kenmore dryer keeps burning out the small fuse every 60 days. What could be causing this?
Answer Hello Ivette,
The small fuse is a thermal fuse. This means that the fuse is opened by high temperatures. There are two things you can do. First, check the exhaust duct to make sure it is as short and straight as possible. This allows the unit to get rid of the heat so the thermal fuse won't blow too easily. The other thing, if the first doesn't work, is to replace the cycling thermostat. The cycling thermostat should open before the thermal fuse gets hot enough to open.
I have ordered a new Thermal cut-off . It is the small one I think 250 degrees. Can I tape the ends together until I get the new one, or is that dangerous?
Answer Hello Gary. No, it is not safe or recommended to tape the two wires together. You need to wait until the new cut-off 279769 arrives to install the part and run the unit.
Dryer only heats every once in awhile. Heating element tested and good, fuse good. Replaced both therostats. Blows cold air
Answer Hello Terri. It sounds like either there is a wiring issue, or the timmer or motor is bad. You will need to test and see where you are loosing the voltage to the heater at. Be careful, you are dealing with live power doing this test. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
My Kenmore heavy duty drier is not heating fully, takes over one hour and a half to dry a full load. The heat is working but not at full intensity.
Answer Scott, The thermal cut off, is a "one shot" fus3e system, once it opens it stays open, and the dryer would not heat at all. The first thing to check in your case, is the exhaust vent system and vent hood, You need to check and clean any lint build up in the pipes, check the hood and flapper for damage or collapse, and any flex venting for kinks. Good Luck and Thanks
