UPDATE. Thanks, kdog. Yes, for these latest tests, I removed the vent from the dryer and airflow is really good but no heat at all.
I think I am almost there, and if you can hang with me I would appreciate the help! This may be long and I apologize.
Ok, I picked up a continuity tester tonight as I really want to get the part tomorrow if it is a part I need. First off, get this. Like I explained earlier, being a newb, the first thing I thought of when the dryer was taking forever to dry things was the heating coil so I ordered a new coil without even knowing I could test it to see if it was bad, I installed it and while it worked we still had the same long drying times problem. I kept the old one just in case it was ok. Tonight, as part of the troubleshooting, I swapped out the coil for the old one and still no heat. Then after getting the tester I was testing the new coil for continuity and could not get positive continuity. I then noticed that a portion of the coil wire from one of the terminals going to the coil was missing!! I noticed black on the metal near where the coil was gone, so the wire just disintegrated! So the incident today where I had heat in the dryer but hadn't been using it I am assume is related to this somehow. Here is my suspicion. When I installed the new coil last week I noticed that the leg of the Hight Limit Thermostat (High Limit Thermostat
) that goes over the one terminal on the coil was kind of loose and I tried like hell to crimp the damn thing on with a needle nose but it never felt tight. I wonder if that loose connection caused a short?
Anyhow, I then tested the old coil for continuity and it tested fine so I put it back in the dryer. I also crimped that connector on the High Limit Thermostat before putting in on the terminal and it is rock solid tight now.
I then test for continuity for the following:
Thermal Fuse: tested fine.
Hight-Limit Thermostat: tested fine.
Thermal Cut-off: Failed, could not get continuity.
Cycle Thermostat: I did get continuity on two legs but not the other two, however I do not know if I am testing correctly. Here is a link to the Cycle Thermostat: Cycling Thermostat
Now, I got continuity on the two larger terminals which in that picture is the two terminals on the top and bottom (harder to see because they are pointing toward the viewer), but the other two, smaller brass colored terminals on the left and right toward the center, I did not get continuity but I don't really understand what those terminals are and if they should even give you positive continuity. Anybody know?
All that said, the Thermal Cut-Off failed to give me continuity. Could that be the problem here? Any chance that part was damaged when the short on the coil happened? Can a failing Thermal Cut-Off cause longer drying times?
Thanks so much!!
