I have Jandy AE-TI 2500 Heat pump about 5-6 years old now. I just turned it on for the start of the season a couple days ago. Ran for couple hours and was producing warm water. Then it shutdown, and was displaying the low pressure REF Fault. Sound like it was on but fan wasn't spinning.
I recycled power a few times. Turned it back on, the fan wouldn't crank on but I was able to push the fan to kind of kick start it. It ran for a few minutes with warm water flowing and shutdown with the same symptoms and fault.
I notice that the coils were beginning to freeze/frost over as well. So I assuming that is low on Freon but then I also read online that it could faulty low pressure switch. I’m just trying to determine which to look at or try first. Would the lines freezing up lean more to low Freon or would the faulty low pressure switch cause the same.
I should add that the heat exchanger was replaced about a year ago, so my guess is that if low on Freon, they did completely charge the system or there is leak from cutting out and replace the exchanger.
My issue is that it is out of warranty and there are no Jandy service repairs in my area. When it was in warranty they had to send a regional tech down from New Jersey to VA to fix...only after a bunch of fighting and threats.
I have a couple HVAC people I know that can probable charge it for me, but my other question is that according to some of the specs I read the AE-TI has R22 freon, however on the compressor on the unit it says use R22, 410a, and a couple other at max psi of 500. Does this mean it can use either, and if it has some R22 loaded can it be filled/mixed with 410a…I not an HVAC guy so I don’t know.
Any help would be greatly appreciated!
Thanks!
