Thanks Brian. Previously the bed would shut down randomly and in order to get to restart breaker would need to be reset and bed would start after fan shuts down. Now fan runs constantly and bed will not start. I've checked power and all connections are OK. I checked the relay and it is opening and closing properly. According to the prosun trouble shooting guide when cooling fans run constantly replace 3 minute cooldown timer but I couldn't locate. I don't know if it is located on the control board or is internal to relay. I think its probably the timer. I'll call prosun to see if they can help when they open. Thanks again.
