Hi All,

Been attempting to fix a dryer. My wife first told me about the issue a few months ago. Problem is for a regular size load it takes at least full 7- min cycle plus another 30 minutes.

Things I have checked:
Dryer hose vent is < 3 feet
Dryer hose vent is clean
Exit vent on the outisde of the house is clean
Continuity on the heating elements is good
I have cleaned the dryer internal vents as best as possible

The most interesteing thing is the exit temperature behind the dryer, tested with a meat thermostat, registers ~100F or lower.

Not for sure what to test next or what part could have failed in that manner.

The exit temperature I previously mentioned was for Low temperature setting.

With temperature knob set to high exit vent temperature is maybe as high as 120F-100F.

Forgot to mention I did test the electric connection outlet and it meausers 240V.

Hi.

I don't know how accurate is your thermometer, but the thermostat is set for 155 F*, so you should read close to this temperature. If you are sure in the accuracy - replace the cycling thermostat Part number: 3387134
Part number: 3387134


By the way, the 37 min drying time for regular load is good.

Here are the breakdown diagrams and Bulkhead Parts, Optional Parts (not Included) parts for Roper RED4440SQ0 - AppliancePartsPros.com

Post the results.

Simon.

Oops that was a typo, I meant 70min cycle plus another 30min nearing some where ~100 minutes for a medium size load.

Let me see if I can find a more accurate thermometer.
