Jandy Pool Heater

[mikecozier]

My Jandy heater will work in pool mode, when I switch it to spa mode, it will work then shut off after a few minutes. Last week I took apart the Jandy filter to spray the cartridges. Think this could be a pressure problem?
Thank you,
Mike

Yes, it could be a water flow problem.

What is your filter PSI?

Ended up being the board. After a day the pool wouldn’t turn on the heater either, so when I put the heater in manual mode I saw the temp was reading 138. Did the resistance check on the sensor was fine, board was bad. Replaced today and working now. Thank you to this forum for all the readily available information!
