How to Troubleshoot Heater Issue

[husker71]

I have a Leisure Bay hot tub that's 9 years old and has slowly been losing heating capability over the past year or so. Yesterday it blew the circuit breaker 3 times before continuing to run. Now the heater light comes on but the water doesn't get hotter and it doesn't shut off until I lower the temp setting on the control panel.

What steps should I take to isolate the problem?

Thanks!

First make sure power is off to spa. Then disconnect both power leads to heater and run all other components like the pump or pumps, blower if you have one, and ozone. If the breaker holds your heater would need to be replaced. Most of the time when breakers trip and it is the spa causing it and not the breaker it usually is the heater.

Mary,

The spa runs now with everything connected, and doesn't trip the breaker. It just doesn't heat. Thanks for the reply...
