Title: erratic temp reading on CB5036
Post by: mckeeb on October 23, 2011, 08:30:22 PM

Hi, the digital temperature readout on my furnace can jump down or up just by shutting the furnace door or side door. Like this morning it read 234 degrees which wasn't correct but it had the solenoid closed and was really about 140 degrees.

Any thoughts on this? I had a guy tell me it could be a ground issue or loose wire back in the panel.

Not sure but if all the wires are tight I would replace it asap if this is the aquastat.

Do you have a ground rod installed? If yes, then it might be the controller itself.

How old is the unit? Could it be covered under warranty?

Guys, I may have found the problem. I took the panel cover off today and just started wiggling wires. One wire in particular going to a relay fastened to a shelf inside caused the unit to jump its readings to 2xx degrees then error out. I shut the stove down and tightened the wire along with the other 3 wires that were sort of loose. All seems to be working fine now but I'll keep an eye on it.

Hey good job!. I think it's time for CB to find some new electricians. My problem was with the light senor in Auto mode. Would not work right. Luckily the dealer fixed it before he left. (Wire incorrectly)
