Bought a house with a pool. Pentair EasyTouch and Mastertemp 250 heater. Heater is shot due to mice damage. Bought a new heater (same model) and have it plumbed in for water and propane. Wired it and nothing. I disconnected feed (2 red wires) and tested for power. No power even with the heater led on in the easy touch panel. I'm at a loss as to what to test next..
