Just went through this with my Kenmore. Here's the sequence I went through:
Just for the record: all these should be tested only AFTER the dryer is unplugged
Check all the thermostats for continuity- mine had two plus a high limit "cutoff"- all should show continuity with an ohmmeter
Check the heating element: unplug the leads and check with an ohmmeter- it should read at or around 10 ohms (range of maybe 8-15). If higher of lower, should be visually inspected
Check thermal fuses- they should show continuity
That's the easy stuff.
If all of that is OK, then you have to decide if you have enough skills to do a little more in-depth checks.
Check the motor safety switch (centrifugal switch) for continuity- this requires a fair amount of disassembly to do.
Also , may need to check to be sure that the voltage is correct to the dryer- Not hard, but requires a high level of respect for the potential dangers- 220v IS adequate to kill you.
Best of luck |
