I guess I jinxed myself when I said I never ran into problems with my Rack for the 6+ years I've had it
I started spot cleaning my tubs today when I thought the tubs felt warmer then usual over the heat tape area. So I got my temp gun and checked and yup.
Higher then it is supposed to be. Not "fatally" high (thank god) but not good..
Quickly unplugged the heat tape and checked all the snakes. Thankfully all were in the front of the tubs, away from the warm end. All look fine to me, no neuro signs, all look strong, alert. Normal muscle tone and reactions.
Found the problem. The probe from the thermostat was glued onto the heat tape and the glue broke off. The probe hung next to the heat tape. Thankfully it was right next to it, which must have kept it from going to high.
This rack has the heat tape underneath the tubs in a recess, then going up the side and under the next tub, etc. The probe was fixed on the tape along the wall, not under a tub.
Its fixed for now, and I hope I dodged the bullet. When I spot cleaned Saturday night, all was well. I am checking temps periodically, but not daily. I have my hands in those tubs almost every day, so I could tell the temp. difference as soon as I had my hand in the tub.
I'm going to check the probe daily from now on as well as hit a tub with the heat gun once the day.
Hopefully they are and stay fine.
