We are starting to get into cold nights and the pool and spa are kicking in to freeze protect mode.
We have had the pool for about 10 years and I've never noticed the blower coming on during this mode. Could be just that: I've just not noticed before. Also, the light comes on in the spa during freeze protect. We do have a pool cleaning company that cleans our filter and also does a weekly clean. I'm thinking they may have changed the settings? They, naturally, want to charge $85 to diagnose.
Thanks for any help you can give.
