Hi,
I've been here before for help with the same dryer.....got 5 more years out of it with help from this forum.
Now, the dryer heats up, but then then heat goes off after a while.
I opened it up and found the inlet side of the blower was clogged full of lint. Vacuumed out all other lint and started it up. It heated up so I thought I was good, but not so.
I disconnected the vent hose and turned the dryer on near the end of the usual cycle. It got hot, but I decided to turn it off and set the timer further back in the cycle to see when the heater is stopping. When I started it back up, the heater never came on.
I let it cool completely and started it back up. After 45 seconds the heat came on, cycled off, then on, then off for good.
Checked the resistance on the two "sensors" ( one pink, one blue ) at the bottom of the dryer, both were 0.5 Ohms.
Checked the resistance of the coils:
2 pin: 1.2k Ohms
3 pin: a hair over 1.4k Ohms between pins 1 and 2 ( as you look at the coil ) and 575 Ohms between pins 1 and 3.
But I read somewhere, you have to check these resistances when it's been running for a while?
After doing the above, I put it back together and watched for the glow of the ignitor. Had to do this with the top off, the bottom is solid on this machine. It would glow, but no ignition. Before doing the coil checks, I would get ignition and heat for two cycles, then nothing.
I checked the parts list for any temp/heat control items and there are six (that I could see) for this model:
Dual coil
Heat detector
Cycling thermostat Hi Temp
Thermostat, Op Hi
Thermostat, Op Low
Temp switch
Before throwing parts at it, are any of the above a standout suspect, or does this sound like a timer issue?
I'm just trying to make this thing last until the end of the year.
Thanks for your time.
