I have a MasterTemp 250 propane heater which I installed about a month ago. The heater has ran for no more than ten hours to date. It is installed indoors to heat an indoor pool and is not exposed to the elements. The heater was turned off for the last week. I went to turn the heater on today by pressing the Pool On button. Immediately upon pressing the Pool On button, both the Pool On and Spa On lights began to blink rapidly. No other error lights are on on the display or within the unit. I have verified that the proper voltage is supplied to the unit and that the correct voltage plug is in the unit and making contact. As I mentioned, the unit has been working fine until today. I have reset power to the unit as well. The instant power is supplied to the heater, both lights begin to blink rapidly. Nothing is ever displayed on the digital readout either.
Any advice would be greatly appreciated. Without having any sort of indication as to the issue, I need some guidance.
