Miele WT945 Dryer Problems - Stage 1 fix


The immediate ‘fix’ is to reset the thermal cutout (the button in the centre of the round sensor fitted on the right hand side of the long rectangular heater box atop the drum). This restores heater power, which the cutout will have tripped out due to the absence of airflow through the heater overheating it. Then, spin the fan motor (at the top rear right hand corner) back and forth by hand to free it (it will be stiff and graunchy at first but quickly frees up. Needless to say, please remember to disconnect power before attempting this tasks otherwise you are in danger of losing fingers. Once you’ve done these two tasks, put the power back on, KEEP AWAY FROM THE MOTOR and try a drying cycle. You should see the motor spin happily and the drying commence. Also beware of the heater box which will quickly get too hot to touch (don’t worry, this is normal). While this fix is easy and effective, and may well keep you in business for months at a time, unfortunately it’s not tackling the root cause, which is a steady fluff/goo buildup in the fan box itself, which impedes both airflow and the rotation of the fan. Oiling the shaft of the fan probably won’t help – the problem lies deeper in the fan box itself.

(Note that the seizure problem is nothing to do with the fan motor itself – this is perfectly OK and will spin freely if you dismount it from the unit. It’s the dryer fan that the motor is driving (through the belt) that is stiff, not the motor. So don’t waste time fiddling with your motor (unless it’s obviously bust, but this is unlikely) despite it being temptingly accessible.)

A Carrier mod # 24ANA760A300 Infinity with an error code #72 high stage thermal cutout, What causes this?

if it's a thermal cutout that's mounted on the circuit board you may have to replace the whole board. I don't have the carrier error codes at hand. But a "thermal cutout" is normally found on the compressor. One advantage of the old (before digital) systems is that the controls were all separate. So you could replace a bad high pressure switch or contactor. Without having to replace a expensive circuit board that held most of the controls.
Not to mention being easy to damage by power surges and lightning

how to replace thermal fuse/flame sensor

GE JES 1358 WK 01 microwave:
I recently had the same problem with a "flame sensor, " aka "thermal switch." My microwave is a "throwaway" model, very few repair parts available. I didn't want to replace it, so I did a little bit of research into thermal switches. I actually found one that would replace it for about $5 (plus $5 shipping).
Mine uses a "bimetal" thermal switch. There are three kinds of bimetal thermal switches: automatic reset, manual reset, and "one time use." The really interesting thing is this: the "one time use" resets (!!!) if the ambient temperature is below 0 degrees C, or 32 F (freezing); or, in some cases, -31 C, or about -22 F.
I put my "dead" flame sensor in the -10 F part of the freezer for about 20 minutes...
Checked it with my multimeter, and the once-dead sensor now read continuity (zero ohms)!!!
Reinstalled it in the microwave, and now it works fine.
So if you have a dead sensor- try freezing it...

maytag dryer ... where is the thermal reset button???

thermal cutouts, thermal fuses, thermal resets, are not resettable, they are a one shot, last ditch, protective device.
fail once - wear,
fail twice - you must clean the lint out of the fan, and exhaust duct before the house burns down.
the thermal reset is a device like this 2ce0a6a.jpg, or this61220a5.jpg fitted on the fan housing.
conduct good,
open circuit fail and replace.
the local parts guy has them, there are only a few that fit multiple models it does not matter what brand is on the packet

4a10230.jpg clean
0787faf.jpg dont clean
a869f54.jpg the exhaust ducting must be clean to the eternal wall vent

WT945 Dryer doesn't dry

check that the lack of air flow hasn't tripped out the thermostats. bypassing them will confirm the element hasnt blown out. but do not keep them bypassed as a "repair"
