chalky Posted September 23, 2019 Report Share Posted September 23, 2019 I have a hotspring vangard spa that is not heating. I have replaced the thermister and no change. The heater measures 36.6 ohms when tested. Does this mean it is dead? The reset button on the side of the heater doesn't appear to be popping out even when the spa is emptied. I am about to purchase a new heater so do you think this is the issue? Quote Link to comment Share on other sites More sharing options...
Hot Spring Official Posted October 2, 2019 Report Share Posted October 2, 2019 That ohm value is too high. You should contact your dealer for service to ensure you get the correct heater to keep your spa operating correctly. Quote Link to comment Share on other sites More sharing options...
Aquastarman Posted October 2, 2019 Report Share Posted October 2, 2019 Before you Replace the heater test the continuity with a digital VOM you should read 11 Ohms for the 5.5Kw heater and around 16 ohms for the 4Kw heater. Hotspring problems are extremely difficult because the system does not offer trouble codes or even blink codes for that matter Quote Link to comment Share on other sites More sharing options...
