Can a hot spring heater relay board be repaired?
If your voltage reading was lower than 100 volts, then the board is damaged and has to be replaced. It is not repairable. Sometimes you can see visible smoke residual between one or more of the black relays (relays are shown above the probes on the Step 9 picture).
What should the voltage be on a spa heater relay board?
My spa plugs into a 120 volt outlet and the voltage reading was between 110 volts-130 volts. Your heater relay board is okay but your heater may not be. Contact us so we can walk you through the next steps. My spa is wired 240 volts and my voltage reading was between 215 volts-250 volts.
What is the heart of a heater relay?
A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current. (heater or motor) The heart of a relay is an electromagnet (a coil of wire that becomes a temporary magnet when electricity flows through it)
How can you tell if a heater relay is bad?
If one pin has voltage but the other does not, then replace the relay. Place a voltmeter lead on each load-circuit output pin. The voltage reading should equal the voltage reading at the input pins. If not, then replace the relay.

How to replace a heater motor switch or relay?
Step 1: Replace the switch. At this point you should have the switch in a position to easily disconnect it. Be careful, there are usually locking tabs on the connector that have to be squeezed before it will release and pull off. The plastic connectors are brittle and break easily.
What should I do if my heater relay is not working?
Turn on the key and try the blower. Some relays may not activate until the car is running and have a built in delay so you may need to start the engine and wait a few seconds to see if your repair was successful. Depending on what you drive, this job could be a breeze or a nightmare.
