Thanks for the suggestions. I couldn't understand why I was getting resistance and voltage at the heating element but yet no heat, just wasn't logical. After poking around for quite awhile it seems there was just a little too much rust around the connectors and it was preventing it from flowing through the element. It was getting bare metal on metal but I guess just not enough. Anyway it's heating a little now, although it tops out at around 85 degrees so I'm going to go buy a socket and try to pull them out and see what kind of shape they're in. Anyone know what size socket I need for a 5500w element for a hayward/comfortzone? Looks somewhere in the neighborhood of 1 3/4"

Sorry, I was measuring the current wrong, both heating elements seem to be getting enough power. I took out the filter and still no heat. I'm measuring the voltage at the terminals on the heating elements so there shouldn't be anything wrong with the sensors right?

I've got a heater that uses 2 4000w elements in it and one day it decided to not heat the water at all. I've checked the voltage at both elements and its getting ~230v. The only thing I can find wrong is that it's only drawing about 10 amps but the resistance across both of them is around 12 ohms so I thought that meant they were still good. I'm trying to pull them and see what kind of condition they are in but it's not really cooperating at the moment. Seems really strange both of them would go out at the same time. Any ideas?
