What should be done if the UltraHeat® Tank Heater is not working?
• Check the 13.5 VDC power switch and make sure it is in the “ON” position, or make sure the 120 VAC power cord is plugged in. • Check the 13.5 VDC fuse, 13.5 VDC circuit breaker or 120 VAC circuit breaker for the RV’s converter or shore power extension cord, make sure the fuse is not blown or the circuit breakers “OFF”. • Check all wire connections, crimp cap connections and all power wires. There must be good mechanical connections between all wires and all wire insulation must be undamaged and whole. • Check the appropriate power source to confirm that either 13.5 VDC power is available from the converter/battery system or 120 VAC power is available from the shore power extension cord to the RV converter or extension cord for the 120 VAC Tank Heater.
