Dryer Runs but won't heat
« on: August 29, 2013, 02:11:32 PM »
Hello!

I have a problem with my GE Front Load Dryer, Model# dhdvh52ef0ww
The dryer runs but will not heat.  I have checked the breaker, tested the outlet and the wires coming into the dryer, and checked the cord.  I tried to find a solution on YouTube and took it apart and tested all of the thermostats.  I have posted a video with what I found here:    I still don't know what is wrong since my dryer is very different from the video I saw.  Any help would be greatly appreciated.

BTW, this is the closest diagram I could find to my dryer inside.  I found this after I made the video which is why I had no idea what I was calling anything.  http://i160.photobucket.com/albums/t200/Zenzoidman/Dryers/ge_dryer8_newstyle.jpg

Post model # But the last thermostat with no reading is bad.Heaters are sagging also make sure vent is clean.

GE Front Load Dryer, Model# dhdvh52ef0ww

When you say the heaters are sagging, do you mean the coils?  We checked all of the vents yesterday and they were very dirty so we cleaned them and tried it again and it still didn't work.

The last one that I refer to in the video that doesn't show connectivity through itself doesn't look like a thermostat.  Do you know what type of part that might be (if that's the one you are talking about).

Sorry I am an electricity idiot so I don't know any terminology.

Thanks so much for your reply.  Not sure about the other part you were talking about.  The last thermostat I tested at the top left had a reading when I tested it by itself.  It did not have a reading when I put one probe on the thermostat and one probe on the heating element.  Then I tested those two prongs next to the thermostat (itself) and get no reading, but I don't know what this part is...do you?

I am looking up parts on web site looks like last thermostat that had no reading maybe a thermistor and what i told you that it may be bad maybe wrong .I what to watch that video again and look up parts # on parts site.Going to need a little time.Ill get back to you.

Yes that part is what you call a thermistor and works on temperature change so you would have to know the ohm valve at room temperature and also at different temps.That would be on a diagram on the dryer somewhere .So that open reading could mean nothing at this point.If it was a open circuit on any of the others that would mean it was bad.That one works differently and probably is not your problem.On a no heat problem you need to check for 240 volts coming into dryer first to make sure you have that.As a motor only needs 120 volts to tumble dryer and you think you have right voltage but don,t.Check for burnt wire on the gray plug were it connects to dryer and also for 240 volts there.

Wow...thanks for that manual...It states:

Inlet control thermistor resistance values:
80 ! at 86F (30C)
100 ! at 77F (25C)
120 ! at 69F (20.5C)

My dryer is actually outside so it is about 100 degrees F right now.  Would this be enough to drop it down to 0 ohm?  Should I disconnect it and bring it inside to test it?

Also, I did not check the outlet control thermistor so I am going to run out and check that.

Even at 100 degree you should get a reading but pull it out and take it inside to see if you get a reading.Did you under stand that your motor using 120 volts and heaters needs 230 to heat.So you can tumble and get no heat???

Yes.  I have 240 at outlet and on the wires coming into the dryer.  I don't see any burnt wires.  I didn't get a reading on the outlet thermistor either so I am going to bring both those in and test.

Outlet thermistor has a very high ohm reading 10,000 ohms at room temperature .You got to be on the correct scale on ohm meter.So far it looks like inlet thermistor is off.As you see from the manual its a very complicated dyer just to dry cloths.

Got to go now hope i help you out some.This could be anything from a bad control board or maybe that thermistor with the no reading.Basic first and cheapest part to buy next.Let us know.Good video you made i must say.

Ok brought both inside. No reading on inlet or outlet thermistor.  Digital voltmeter is set to the only ohm setting (I think).  It shows the ohm sign/like a little speaker sign
