How do I test the heater thermostat? Is it normaly opened or closed when cold?
Answer Hello Richard,
It should be closed until heated to the specific temperature rating of the thermostat at which time it should open until cooled.
My dryer works fine on medium and high heat settings but on low or delicate settings the clothes come out damp or not dry at all. All venting is clear.
Any suggestions where to look next?
You will want to check the selector switch to make sure that the switch is good. Test continuity for the fabric selector from pin 1 to 2 and make sure that there is continuity when set to delicates. If this checks ok then the issue may be caused by a failed cycling thermostat.
Blowing thermal fuse at heating element. Both limit and cycle thermostats check ok. Vent clean, heating element good. Found booster heater at cycling thermostat open. Would this cause the heating element to over heat.
If the cycling thermostat is open it would not cause the heater to overheat. The cycling thermostat being open would cause the heater to not come on. The high limit may not be opening quick enough which could cause this issue to occur.
Heater Thermostat was getting really hot but the heater was not heating the dryer air. Is this a sign that the heater thermostat is bad?
Answer Hello Nathan. Check and make sure you have 240 volts coming to the dryer. Check and make sure the unit is not set to Air Fluff. Also check the heater and thermostats and see if they are good. You can test these with a multi-meter TJMA-DM1. They should read closed for continuity.

My dryer was running. Suddenly the motor stopped. No power.
Answer Hello Carol. You need to test the door switch and the thermal fuse LA-1053 on the side of the heater housing. If bad, they will prevent the dryer from running. You can test this with a multi-meter TJMA-DMT3.

Dryer is making an intermittent vibrating sound coming from the blower housing. Very random, dryer is still drying normally.
Answer Hello Alex,
You will want to pull the cover from the blower housing and look at the blower wheel to make sure that it is not damaged. Also check to make sure that there is not a heavy lint build up on the blower wheel.
