Pentair Ultra Temp Heater issue - turns on but will not heat

[jtthomas10]

Pentair Ultra Temp Heat Pump installed 5 years ago. I have had the capacitor replaced twice (by technicians) and I just replaced the control board. Everything appears great. It turns on, the blower is spinning and moving air, but no hot water. Inside the house, you can actually "see" it pull electricity because we get like this 5 second mini-brown out like you do when there is a new big draw on the power. No errors messages. Flow seems fine. I guess it could still be the capacitor at this point...again...probably need to test the guys actually replaced it last time.

Pentair Pool Pump and panel as well. No spa. Self-cleaning. Chlorine not salt.

Been reading the manual to see if it's something stupid in the config but not exactly sure where to start.

Looking for a list of things to try out, i.e. troubleshooting tests, things to wiggle, error messages on the panel diags, etc. I can handle minor electrical work if needed (like replacing capacitors and boards and doing testing).

It's just weird because on paper it looks fine...but it's obviously not.

Thanks for any help or info.

I have had 3 different "pool guys" check and work on it. The last guy said, "well it turns on..." jeesh. So hard to find certified intelligent service technicians in Arizona. Everyone with a pool net and some chlorine tabs says they are an expert.

You need someone familiar with A/C repair to check for proper refrigerant level and pressures. Your heat pump is just an A/C compressor unit and requires someone with the proper training to say more than it "turns on." That's completely out of the experience of a pool tech. Two years ago my A/C "turned on," but no cooling until a small leak was repaired.
