Okay, I’ve done a ton of searching, and have even used this site before, but this is my first post. Previously, probably a couple years ago, my ignitor went bad. I replaced it and all was well. Now, no heat again, I suspected the ignitor again, but it is good. It does not come on at all. What should I check next? Thanks for any info.
Greg
As far as checking the ignitor, do you just check for continuity, or resistance also? Thanks.
I checked the thermal fuse and thermostat (?), at the back of the dryer and both had continuity. There was no resistance read. Any other suggestions? Posssibly timer? Thanks.
Greg
Hi Greg,
Check for continuity the thermal cut-off and the high limit thermostat (#15 & #16 on the [B]diagram[/B]).
The high limit thermostat [part]AP3084674[/part]
The thermal cut-off kit [part]AP3176214[/part]
includes the new high limit thermostat
Here are the breakdown diagrams and replacement parts for the Whirlpool dryer [MODEL]MGD5620TQ0[/MODEL]

Hey Gene,
I checked both of these parts yesterday, and there was good continuity on both. Any other ideas?

Check for continuity the flame sensor (#32 on the [B]diagram[/B]).
If there is nothing wrong then check for continuity between the "R" and "BK" timer terminals while the timer is "On".
Be sure you removed wires from any tested part. If you did not then you have to retest them all.

Thanks for the info Gene. I will need to retest, as I didn’t unplug the wires. On another note, where is the thermal fuse? When I was checking for continuity, I checked the thermostat and the thermal cutoff, but I don’t know where the thermal fuse is. I have the schematic, so I’m going to trace the blue wire. Thanks for all your help.
Greg
Greg,
This model does not have a part called thermal fuse. Instead it has a thermal cut-off.

Thanks Gene, I was just going off the schematic.

Gene,
So I rechecked continuity on the thermostat and thermal cutoff, and all was good. So, I started checking the schematic again, and indeed found that I do have a thermal fuse, with two blue wires attached. I checked it, no good. So, I went ahead and jumpered the two blue wires, started the dryer, and I have ignition now. Here’s a couple pics of the fuse and schematic sections. I guess I need to find this part now.
I do not know why this part is not shown on the diagram. The diagram is provided by the manufacturer. I found the correct part numbe for this thermal fuse by the picture you posted.

Hey Gene,
Thanks for all your help on this one, it’s truly appreciated.
Greg
Got the fuse put in yesterday, all is well. Thanks again Gene!
You are welcome. I’m glad you were able to fix it. Thank you for the feedback and good luck with your dryer.
Gene.
