Company Logo
Action Spa Repair LLCThe spa was initially powered off upon arrival, but was successfully powered back up, although it displayed an SN error. After installing a new sensor, the error was cleared, and the spa was tested with the heater and jet pump running, pulling 24 amps. The new high limit and temperature sensor were installed, and the spa's functions are now working properly with no further issues observed.
