Kitchen Aid Dryer Not getting Hot
« on: December 09, 2008, 09:48:36 PM »
Model Number: KEYE777BWH2 icon


i tried reading through some of the older threads and found some useful info, but i could use more help.

Our dryer seems to work normally except for the heater not working.  

without troubleshooting, i went out and got a new element for it.  switched that out without a problem, but it didn't fix my problem.

i read about the thermal fuse, and checked it for continuity. it has continuity.

i checked the resistance of the new element and its 10 ohms, i think that's where it should be...  using my 'hot stick' which shows current only, not voltage, i have current at all terminals, the heater, the 2 thermostats, the fuse, the other terminals near the exhaust...

i would think, that with the element showing current passing through it, that it would heat up...but then i just tested the air dry setting and it has current at that setting, so...

I'm kinda at a loss. i think there are other things i should be checking. i think i have 220 at the outlet. i used my multimeter on the power cord's terminals, touched a terminal and ground, got a reading around 110 for 2 of the 3 terminals... not sure if that means i have 220..

any insight on the next step to take would be appreciated.

Thank you,

Andrew

Above the heater element on the upper portion of the heat element chamber is a 300 degree high limit. if it is open you will not have heat.
Part number 8(schematic bulkhead parts for K-aid dryer etc etc etc)on the old appliance parts pros lookup AP3094244 21.51 plus tax title and freight. NOTE: replace both the lower and upper guys because the upper one blows at a higher temp than the lower dude so the lower guy didn't do his job.

read about the thermal fuse, and checked it for continuity. it has continuity.

Be sure and  check  the other thermostats as well, including the hi-limit. Your voltage at the wall plug may be the problem. I find it easier to take the back plate off the dryer instead and do your checks. A hot stick is not a voltmeter and will not confirm 240 volts. There must be 240 volts between the 2 outer terminals on the wiring block of the dryer where the cord attaches. To check the wall voltage, see the pic below:

"hot stick" shows voltage

also check the Hi-Limits JW mentioned.

its the hi-limit...
but why

Disconnect the Vent and check for good air-flow

Should be rigid metal Vent

Foil Duct Tape

NO plastic
NO PVC
NO screws

Vent temperature should be:

With an empty load, Timed Dry, High Heat
It should cycle somewhere between 135F and 160F

Excellent post by Reg, make sure your dryer can properly breath or you will be buying more hi limits. Give it a good cleaning.
