I've checked continuity of the following parts using an ohmmeter: 3404154 fixed thermostat - closed 3399848 thermal cut off fuse - closed 3399849 thermal fuse - open There's a label inside the machine that tells me that a blown thermal fuse also requires the replacement of the "operating thermostat/thermistor". But I am having trouble tracking down that part number. Any suggestions? Also any step by step suggestions for diagnosing the original cause of the problem?

Model Number Locator If the thermal fuse is the one on the blower then I do not know why they are recommending replacing the operating thermostat. The most common cause of this fuse blowing is a dirty or malfunctioning vent system.

Here is your thermal fuse and the operating thermostat Part number: AP2947182 Part number: AP2975271 Click on the picture for more info. They recommend replacing both because they feel that the thermostat should have opened and shut off the heater before the fuse blew, For the cost of the thermostat I would also replace it. Note: What wires attach where as it is a 4 connector thermostat. 2 for the contacts and 2 for the internal heater so it is important that you do not get them mixed up. Clean and check your vent system. Also you should check the heating element. Check the heating coil. Unplug the unit and both wires to the coil. Check it with a meter, should be around 13 to 20 ohms. Then check from each side of the coil to the case/frame, both should be infinite ohms (open). If not the coil may have sagged or broken and is touching the case. This can cause it to run on high and the thermostats cannot regulate it so the thermal fuse blows. File Attachment(s): DQ2.pdf (370kb) downloaded 40 time(s).
