Please don't fall into the logic trap of measuring one heater terminal to ground or neutral. It doesn't work that way. To meausre heater voltage (aka the complete circuit being made) you MUST measure between the two heater terminals.

Here's a diagram for you intense folks...

Please follow it. If you don't understand how to make these measurements after looking at this, then please call us.

I'm not getting any heating action or the unit is not telling it to heat. do I check the element with ohms tester? what selection do I make on the meter? 200, 2k, 20k, 200k, 2M?? I checked it on 200 and it read 10.4, this is with the power shut off.

How do I know if the element is bad??

where can I find the ohms range for the thermistors in my 99 hotspring Grandee? I already replaced them, but I have this need to know which was causing the issues, so I wanna test them...

thanks!
