Dryer not blowing hot air...

[dbhost]

Looking for why. I have good power, the dryer tumbled,element and thermal fuse test good... what else can I look at?

[Dal300]

Checked the thermostat? Possibly a relay is stuck open/closed.

No real answers, just thought it might be a direction to look in.

Some dryers have a switch on the motor that "enables" the heating coil.

There is often a schematic in a pocket if you take off the cover over the timer compartment. I'd trace the power through the circuit using the schematic.

FWIW, last time this happened to our dryer it was a cut wire - it had been pinched during manufacturer and after 30 years, wore through the insulation.

I went through this a couple of months ago. The solid state thermal fuse blew. Sears parts clerks suggested replacing the solid state thermostat at the same time - they said it's what their guys would do.

+1. That fixed our last dryer.

Always a good idea to check your vent.

[sparkeyjames]

If it's electric check to see if your getting 220 to the dryer. I had a faulty
section of my breaker panel and the dryer was getting short changed.
The motor would run but no heat. Swapped things around a bit and
bingo.

Yeah that's the first thing -= got me a while back; the lint completely plugged the vent hose and cover.

That happened to me a while back. Took the darn thing apart and couldn't find the fault, not that I really knew what I was looking for. Put it back together and figured that a new one was the way to fix it. Then........ noticed as I was wiping the finger prints off of it that there was a dial that went from delicate knits to Hades. Seems that someone had turned the dial and I never thought of checking it. Sort of like is the computer plugged it? Just thought I would mention it

I've known foolish and I've known stupid, it's foolish and stupid that makes for an interesting friend.

Actually tried all the settings first...

So far I have tested the heating element, the hi limit thermostat, the thermal fuse, and the cycling thermostat. I have also checked the feed line / block and it all tests good... As far as I can tell the dryer itself is okay, which leaves me with 110V at the outlet? Does that sound right? How do I test that?

[chopnhack]

Db, 110 at the outlet? Dryer's are usually 220v, with your dvm, what wires or recep. holes are you probing?

[unknown poster]

Are you getting + to both sides of the coil? Disconnect the coil, hook your voltmeter to a known good ground and check the voltage to the coil. If not check the wiring diagram and work your way backwards to find out where the power stops.

Also check the resistence of the coil, is it shorted?

I'm not an electrician, I'm just a guy who tries to fix my own stuff when it's broken. That's how I would approach the problem.

[dbhost]

I got it figured out. For some reason the thermal limit fuse would test good, then test bad, then test good... I did check the line coming in and I am getting 122V at each leg. A little over 240V but within tolerance I believe.

I have the fuse and thermostat ordered (they are a kit) so with any luck I will have a fixed dryer by the end of the week...

[unknown poster]

Now you get the fun job of figuring out why the fuse blew.

Check the vent, lint trap, shorts in the coil. Anything that could make it overheat.

[dbhost]

20+ years of service, and a partial contact break, not quite a complete blow out... There was several sweaters worth of lint behind the thing. I am figuring a good clean out and reassembly, including cleaning out the house duct and I should be good...
