Electric Clothes dryer?

Question

I have an electric clothes dryer. Whirlpool model LE9100XTN0

The clothes have been coming out super hot. Almost too hot to touch. I suspect a thermostat but there are two. One is on the heater box ( part number 3390291) and the other on the blower or exhaust box ( part number 3387134). I checked them with my ohm meter and Both have continuity but I realize one (or both) could still be defective. Which thermostat should I try replacing first? Which one is the likely culprit ? or..... Could it be a faulty moisture sensor or something else ?

Answer 1

In your case...........sounds like it may be about air flow or a blockage........check the easy ones first......good luck

Answer 2

My guess is not a thermostat at all. I think they are doing their job. Your problem is air flow, or the lack of it. Check for lint build up in the discharge, hose, and outdoor vent.

Answer 3

this one is your cycling thermostat,the blower or exhaust box ( part number 3387134, it is diffenitly bad and needs to be replaced, it's possible that the other, which is the high limit thermostat, is also bad, i would just replace the cycling thermostat first though

Answer 4

Based on my own past experience, my husband took my dryer to a reputable appliance dealer we've known for years and ours wasn't drying so they changed out the thermostats and worked fine afterward.

But the repairman said it is always best to replace both because a older unit will likely go bad when a new one is put in. And the cost was less than $10.00 each so your's will likely be around the same price range.

Answer 5

Hold on....open the reat output hose and check to see if; (UNPLUG FIRST!!)

1. Is there a good stong flow of air.

2. any c**p in the output area or the output hose

3. Usually the temp sensors fail and NO HEAT is developed. I would he very surprised to see them fil in a way that allows the dryer to overheat.

4. Is the lint filter clean?

Answer 6

Is one of those a user-adjustable thermostat?    If so, when that one is hot, and you adjust the temp lower, it should change state (i.e. go open if it's closed when cold, or vice versa).  

The one on the exhaust is probably a safety limit switch, designed to shut the dryer down if it gets too hot due to a blockage or stuck user-thermostat.

I would assume the moisture sensor would not be involved in an overtemp situation.

Answer 7

Check the airflow, first.  Filter, housing and the ductwork.  Airflow should be strong and warm, not slow and hot.

Dryers should be disassembled and cleaned periodically as lint builds up inside (and socks have ways of getting into the weirdest places) and creates fire hazards.

Answer 8

first clean out your vent hose.

then if that doesn't help, it sounds as if it's the heater thermostat.  Whatever you do, don't run the dryer while you're sleeping or away from home...
