I recently bought a used Jandy LX Heater - it was listed cheap as "not working - air flow switch error", so I figured I scored and could put in a new-old-stock pressure switch for like $30 from ebay. Once I got it home, I discovered the problem was with the blower itself - it would just humm...

Update: I blew out the line with compressed air, backed the pilot adj screw open more, and was able to get a blue flame with 350mv output. This is enough to keep the pilot open, but just shy of the 400mv needed to open the main valve. I'm wondering if the thermopile is sitting too high and not...

So replace the pilot tubing also ? I'll give it a shot

I'm in a small town in Ontario, the heater came from a few hours away down by Toronto. I found it on kijiji (Canadian version of Craigslist). What's puzzling me, is how the technician missed that wiring problem ? and the pilot issue.. Starting it with an external thermopile, it runs and stays...

Update, the pilot magnet was NOT wired correctly. Upon closer inspection, it was connected to TH instead of TH-PG! It now WILL light and even run with an external t-pile, but still no dice with the existing one. Going to swap out the t-pile and pilot light to see if that fixes it!

Red (from thermopile) = TH-PG White (from thermopile) = PG Safety circuit (t-stat, limit/pressure switches, etc) = TH and TH-PG The valve has a symbol of a coil going between TH and PG. I'll get another picture after. - - - Updated - - - I just wanted to see if once it got the full voltage...

Update: I tried connecting an external thermopile (spare parts I had from another heater), and heating it with a torch. I got it up to 760mv and still the pilot light won't stay lit if I release the button. Maybe the technician tried this same test and it really is a faulty valve ?

Thanks, I'll try cleaning it, then replacing the pilot. The heater is about 8 years old (bought it used from kijiji) - I had to get a gas line run from the meter to the pool (60ft), so I had the technician hookup the heater. I was hoping to get even just 2 more seasons out of this heater (paid...

I have a Hayward H250 millivolt heater (natural gas), and the pilot won't stay lit when the button is released. Two things I noticed: 1) The thermopile seems to be putting out very little voltage - when first lit it starts around 8mv, and after 2 minutes only reaches 18mv. 2) The pilot is a...
