VI - TROUBLE SHOOTING (cont.)
Using a voltage meter set to the 200 ohm scale, you should have a resistance reading of 26 - 30
ohms through each of these heaters. The heater located on the heat exchanger piping should have a
resistance reading of 81 – 86 ohms and the one located in the water flow sensor valve has a
resistance reading of 16 – 19 ohms. Voltage throughout this circuit should be 120 VAC.
Fuses:
This unit has 2 in line (3) amp glass fuses. Remove the fuse and check continuity through them. If you
have continuity through the fuse, it is good. If you cannot read continuity, the fuse is blown and must
be replaced.
