Well, we finally got the tub to heat for us. However, it will ONLY heat when the jets are on. No other time.
So, in order to use the tub, we have to go out some time before and check the temp and if needed, turn on the jets and allow it to heat. We forgot about it one day and it heated to over 106!. WAY too hot unless we were chickens cookin.

We have checked and checked and rechecked things and just cannot figure it out. There is sufficient power going to it according to the tester and the OHM meter.

The heat light does not come on unless the jets are on.

Uhhg!!

Help please?
