Thread: Tripped Breaker
05-07-2009, 08:06 PM #1
I have an older spa that heats up great, but after it heats up, the breaker trips and the circulation pump runs all the time because the thermostat is no longer controlling it. I read some earlier posts and the filter is clean, the water level is at the top of the spa and I can feel hot water circulating out of the jets when the unit is heating. Is it possible that the high limits switch is defective and needs to be replaced? Thanks in advance for your assistance with this.

Are you saying your house circuit breaker is tripping? Or are you referring to a mechanical high limit tripping after the heater has been on for a while? If you are referring to a mechanical hight limit that trips then it is possible that it is bad. If the house circuit breaker is tripping then you have a different issue than the high limit.

If your house breaker is tripping , it could be bad . If you have a amp meter you should not measure more than 80% breaker rating when pump and heater are on. No amp meter, if you have another circuit with the same value breaker,, they can be swapped and see if you have the same problem. If you have the same problem, it's with the spa. SS
