oh no, I dont mean that -- I mean it is not glowing RED like was prior, it is glowing like HALF RED

What components regulates voltage to the coil?
nothing ...
full 220v  normally goes to the Heater ...
check your volatge at the Wall Outlet and Dryer Terminal Power Strip.
Black to White = 120v
Red to White = 120v
Black to Red = 240v

Voltage from the wall is normal, 220V.  The fan and blower are moving air well, but the air is not really very warm at all, 80F, maybe.

Where is the Dryer Terminal Power Strip? 

What components control voltage to the coil?

Like I said, I now have a set of components, and would like to figure out the logical place to start.

Follow the cord into the appliance for the power terminal. The 4 wire control tstat mounted on the blower housing controls the heater. All other components are for safety only and do not control the heat.

1) where the Power Cord connects to the Dryer
2) it's either ON or OFF, gets the full 220v or nothing
measure the voltage on the Heater while it's ON

ok, all voltage measurements are within tolerance.


When this unit is in full operation, and air is flowing over the coil while being powered, is:
  • the coil being fed full voltage and shuts off when it gets above selected heat settings? or
  • the coil goes on for a few moments, then off, then on, (oscillate) to meet the selected heat settings?
I suspect the computer must be to blame, if the other components fail to limit voltage levels.

Interestingly, I replaced the computer a year ago, and find hard to believe it decided to fail...

The heater is turned off and on all during the cycle. When the temp reaches 160f (for cotton) the thermostat shuts down, when the temp drops to 105f the thermostat powers the element back up until drum temp reaches approx 160f. If the blower wheel is clogged with lint or stripped the air flow will be improper EVEN THOUGH YOU FEEL IT COMING OUT THE BACK. On these machines the blower wheel gets loose and causes a lots of grief.

Yeah, I have triple checked the blower due to reports they fail often.

What component would cause the coil to get constant voltage, then (that is, not turn off)?  That seemed to be what was happening last night.

Computer or control thermo?

That is easy Coil shorted to the frame. Very common on this machine double check if the large limit's wire is NOT touching the heater mount. Seen it.

... the coil goes on for a few moments, then off, then on, (oscillate) to meet the selected heat settings
Heater is ON until the Vent temperature reaches aproximatley 160F,
then it turns OFF until the Vent temperature drops to about 130F
The ON /OFF time may be a  few minutes for each

Ok, so here's the thing -- if the coil is ON, it is ON ON, like RED HOT ON, right?

Last night, I was seeing a not at all RED HOT ON, it like a PINK/GREY HOT ON.  I will check for shorts and ground again.

All this technical jargon is getting be HOT.

I am going to mess with it today, and hopefully get my wife OFF my back about it.

You can easily tell if you have a short by unplugging the machine and turning the timer on any cycle, then check to see if you can get a reading from either of the prongs on the end of the cord to the frame. You should NOT get a reading from either prong to frame. You should GET a reading from the middle GROUND prong to the frame.
If yours is a 4 prong cord you should not get a reading from red to frame or black to frame with the dryer unplugged.

After I do a repair on any appliance I always do this check before plugging one back into live power. You never know.

ok, all electrical == no problems.

Heating coil element properly working, both in and out of housing, @ 11+ ohms.

All thermostats replaced.

Computer left alone until all else fails.

Blower housing intact, HOWEVER, air seems to flow THROUGH the front door through a plastic liner which snugly fits against the blower housing.  This plastic liner was separated from the front panel by about a centimeter -- I plied it back in place, and reassembled the housing once again.  I think the insecure fit of the air path to the blower may have been the problem -- I am hoping it is better, since it is impossible to tell from the assembled unit.  I think JWWebster hit it on the head:

If the blower wheel is clogged with lint or stripped the air flow will be improper EVEN THOUGH YOU FEEL IT COMING OUT THE BACK.

While there was no lint build up, and the blower seems to be functioning properly, I am hoping the loose "dust collector dust assembly" is the culprit.

Plugged everything in, and it seems to be working.  The wife will confirm in about 40 minutes.
