Pump runs all the time, Spa is too HOT

• Relay for Pump sticking
• Connector in Common (HOT) position
• Sensor not sensing temperature correctly

HR10 contactor doesn't engage

• Disconnect black wire and touch the opposite side of the white (this tests the contactor and shows that it does or does not engage
• On the switch remove bottom wire and touch the top(if contactor engage then bad air switch if not bad board)

• Not enough time given for it to heat
• Impossible...Heat come from motor;there is not a heater that would activate.
• Cover is not on spa

• Possible fuse
• No power from relay
• Temp sensor not sensing temperature
