Does my Appliance break? Timber Dryer Gets too Hot

Specific failure symptoms include: 1) An unusual smell in the laundry room. 2) The top of the dryer is very hot to the touch. 3) The clothes are extremely hot and wrinkled at the end of the cycle.

Check Cycling Thermostats

When a dryer is overheating, the first concern should be whether the heater element is cycling (turning ON and OFF). An easy check is to set the heat selector to a heat position and turn the timer to the ON position. With the dryer running, turn the overhead lights OFF. Check the back of the dryer (with the back panel removed). On left-hand side of cabinet there should be a visible glow from the heater box. This glow would indicate that the dryer is heating and has the required voltage. After a period of four to six minutes, the heater should cycle off and the glow should fade. If not, then probably the dryer cycling thermostats or adjustable thermostat is not functioning properly. You will have to replace the defective thermostat(s) in order for the dryer to operate properly.

Check Adjustable Thermostat

Some clothes dryers use an adjustable thermostat, which is similar to a cycling thermostat. But while the cycling thermostat employs a bimetal disc to open the circuit to the heating element when a certain temperature has been attained, the adjustable thermostat employs a sensing bulb that senses the temperature outside the dryer drum before the heating element is cut OFF.

The adjustable thermostat is easily checked by using the volt/ohmmeter. Unplug the dryer power cord and set the scale of the volt/ohmmeter on RX-1. Place a probe of the volt/ohmmeter on each terminal of the thermostat. Slowly turn the knob of the switch in a clockwise direction and look for a reading of 0 ohms on the volt/ohmmeter. As the knob is turned to the left (counterclockwise) the volt/ohmmeter needle should return to the left of the scale (infinity). This would mean that the dryer is no longer calling for heat. Abnormal readings would suggest that the switch is defective and should be replaced.

REPAIR PROCEDURES

Unplug the dryer power cord or gas supply before servicing the clothes dryer.

To Replace Cycling Thermostat(s)

When removing and replacing the cycling thermostats on the gas dryer, the repair procedures are the same as was discussed for the electric dryer.

To Replace High-Limit Thermostat

When removing and replacing the high-limit thermostat on the gas dryer, the repair procedures are the same as was discussed for the electric dryer.

To Replace Adjustable Thermostat

To replace an adjustable thermostat in a typical clothes dryer, unplug the dryer, move it out from the wall and remove the screws that secure the console back panel to the dryer top. Remove the screws that attach the thermostat to the dryer console. Remove the thermostat control selector knobby gently pulling off the control shaft and remove thermostat.

Remove the wires from the defective thermostat and remove the thermostat from the dryer console assembly. NOTE: When removing the thermostat wires, note the sequence in which they were removed because they are to be reinstalled on the same terminals of the replacement thermostat. Remove the two screws that secure the thermostat sensing bulb to the dryer fan exhaust.

NOTE: When replacing the adjustable thermostat control, you must mount the replacement thermostat capillary tube with no kinks or binds in the same position as the defective thermostat that was removed. Failure to install the thermostat capillary tube properly would cause the dryer to operate improperly.

Install the replacement adjustable thermostat control by mounting in the same position as the defective thermostat that was removed. Follow instructions supplied by the manufacturer. If no installation steps are provided, reverse the above steps.

To replace the adjustable thermostat of the gas dryer, follow the same procedures outlined above for the electric dryer.
