It also may be time to replace your MiniMax® NT High Limit Switch if all 3 lights on the back of the control board are on and one or both of the switches shows an open circuit (given proper water flow through the heater).
- Compatibility: Fits MiniMax® CH, NT STD with 6800, ST STD with DDTC, LN with 6800, LN with DDTC, TSI with 6800 and TSI with DDTC Heaters
