Roper Element replacement

Monster_Rain · October 11, 2012, 11:38am

Hey, guys. My Roper, Model RES7648EQ2 just stopped heating up. Should I just assume that it’s the heating element, and can you point me in the direction of a good troubleshooting/walkthrough?

Thanks so much in advance.

Well, I tested the thermal fuse, which was fine, and my element had read 9 on the losest setting of resistance. My high-level thermostat is fine, too. I guess I’ll check the cycling thermostat, but I don’t like the way this is going…

Cycling thermostat is fine. Anyone have any ideas?

Have you checked if there is 240VAC to the dryer?

No, but I’m not sure how. I’ll google it. Thanks a lot!

You are welcome.

Yes, it’s 240VAC. It’s not making any damn sense…I noticed, though, that it shuts off when you turn it to the end part of the auto-dry cycle.

Sorry, I meant that it is getting the proper voltage, like 249.

And it shuts off at the wrinkle prevent of the auto-sense dry cycle. This is infuriating.

Hi.

Here what you need to do:

with dryer turned to heat check if there is 240VAC across the heating element (if yes - replace it)
with unit unplugged check continuity of the thermal cutoff, operating thermostat, hi-limit thermostat (replace if needed).
-with unit unplugged open the control panel, set the timer to Timed-regular and check continuity TM-OR,BK-R,T-W.
If everything checks out OK then most likely the motor switch contacts 1M-2M not closing.

Here are the breakdown diagrams and Bulkhead parts for Roper RES7648EQ2 - AppliancePartsPros.com

Post the results.

Thanks again, will post asap.

-OK, No voltage through element while set to heat.
-continuity good for operating thermo and hi-limit thermo
-What I THINK is the thermal cutoff(connected to a red and red-white striped wire isolated in the middle of the back of the dryer), and I think the schematic indicates it as that as well, has no continuity. Is that the right part, or should I proceed to the panel wiring?

Sorry for the double-post.

Thanks again!!!

You are welcome.

Will do. I’m assuming it would be pretty stupid to bypass the cut-off in the meantime?

Simon_APP_Team · October 23, 2012, 4:28pm

HI.

Only to test the dryer. Also, check the venting for any restrictions.

Simon.

Monster_Rain · October 23, 2012, 4:31pm

Works fine when bypassed. Venting is unobstructed. Will post results in the next couple of days.

I purchased and installed the thermal cut-off/thermostat kit and now it works like new! Can’t thank you enough, man. I was gonna replace the damn thing.
