Oh, and when the dryer is set to "Low Delicate" ...the temp ... is ~150 deg F.
When the dryer is set to "High Heavy Flame Broil"... Oven thermometer reads ~175 deg F.
(1) We are looking for average temps, not high points.
(2) If you are averaging 155-160 ish on regular, and a lower temp then that on Medium and a lower temp then that on low, your are probably within specs.
(1) Over thermometers are not known for fast response. I consider the temps shown to be averages.
(2) Ah, but I am getting 150-ish on Low, not regular.
Voltage to the bias heater is 0 on high, ~67 Vac on Med, and ~115 on High. So the temp selector is good.
But check this out: this thermostat is stamped "150F - 25". Which implies to me that it is 150 degs with the bias heater OFF, and roughly 25 deg F cooler with the bias heater ON.
I'm getting 150 deg F with the bias heater ON, and roughly 175 deg F with it off.
So I did some pondering. Since everything generally flows from a single root failure, I figure the order of events was:
Counterindications to this theory: The dryer worked for about a year after I replaced the temp selector and bent the heater wires back into the right shape. But even master AccApp suggested changing the cycling thermostat, so I did.
- 3 years ago the temp selector failed so that the heater always ran on high.
- After a year of that, the heater wires sagged a little and shorted to the case and now it was on high even on fluff mode.
- So I replaced the temp selector (verified bad) and fixed the heater (verified bad) which I eventually relaced on the advice of "Sublime Master" exsearsguy.
- So now I'm wondering if maybe around the same time, the bimetallic thingy in the thermostat got permanently bent from the overheating, and now it reads wrong.
No change. Verra mysterious.
