Went to use it two days ago, it was at 89, thought I had turned down the heat.
Turned heat up, put on jets for an hour, came back, still 89.
Yesterday, left heat in the middle- 100 +, still 89.
This morning- still 89.
The heater must work, I'm in central KS and the dog water freezes at night here....
Some thermostat, control board, or the heat knob assy.???
Not a spa guy, but am very much a fixit guy..
where to start? thanks in advance..
