Temp Sensor Error

[kmc58]

We own a 2019 Thor Aria. Not able to get the furnace to come on and it's pretty cold where we are. On Climate Control Box it is giving us a Temp Sensor Error message. Any suggestions of what may be going on or how to reset it? Thank you!

Looks like you have a bad temp sensor or a bad connection from the sensor.

Greetings and Welcome

Do you hear the igniter clicking? Try disconnecting the control board in the heater for a few minutes and reconnecting.

Do you have other heat sourceS, ceramic, quartz etc?
Someone with more suggestions should be along shortly.

Thank you for your reply.

Purchased this RV in November so we are still in shakedown mode! No problem when we were in VA with it this past December but in TN now and this happens!

Hopefully we can figure out what's going on today.

I am new to this forum but familiar with the Keystone forum. Everyone is so helpful! Thanks again ....

That looks like a loose wire on the sensor somewhere. See pic, there is one of these for the front and one for the back, look under the upper cabinets toward the middle or rear.

Should have two wires behind it. If you have an ohmmeter and can get to the contacts on the back, the circuit should measure about 10K ohm give or take with temp.

The two wires run through the unit (always the long way and always in a conduit) back to your control box. In the back of the control box you should see labels on the lid, this should tell you which wires to look for.
I had one just after I picked up it up new where the temp sensor was a bit intermittent, found a pitched wire in the cabinet right behind the sensor where the wire was. As soon as I pulled it out it looked like somebody bent it bad and then installed it anyhow. Soldered a bit, works great.

Worked until it cleared the curbs on the dealer's lot.

Good luck.

Yes, I'm beginning to believe this!!

Thank you!

On my 2015 Tuscany that is quite similar to your Aria the same sensor in the photo was never connected? Wires were just hanging loos in the wall. Another problem is the crimp connector that joins the wires. Several of mine were not touching bare wire so an open. Do other zones work OK?

We have about come to the conclusion that it must be a loose wire or a bad sensor. We had a local RV repair company to look at it, but with them not being familiar with the unit we have decided to wait and return home to our dealer, for ANOTHER service call! Have had it in the shop more than we have had it on trips!! Our 1st Thor and probably our last!

I appreciate all of your replies!

I would at least take the sensor from the wall and check the wiring before I took it to a service department.
It may be nothing more than a bad connection at the sensor. If the connection looks good, I'd swap the front and rear sensors to see if the problem follows the sensor.

Thank you. We will check the wiring.
