I can't seem to get the pilot lit this year. When I put a flame in front of the tube, I see a flash at the back, but won't stay lit
I thought that I might try that later today. I will let you know how it goes. ThanksMay have to clean pilot assembly, and/or replace the pilot generator
I have removed the tubing, is the nut you refre to, the one that the tubing goes into?Not sure how far you want to go but there is a orfice inside at the bottom of pilot assy. You need to remove the tubing from the assy. and unscrew the nut. If it is severely rusted you have to be careful not to break.
Thanks, I will see where I can source one in CanadaBuy a new pilot assembly. More than likely the pilot orifice is rusted in place and you won't get it out.
Thanks, I think I have the honeywell gas valve,This should be the manual for your heater: https://www.poolsinc.com/pdf/raypak/raypak-digital-heater-product-manual.pdf Refer to the wiring diagram on page 28. If you put one lead of your meter set to mv on the TP or PP terminal of the gas valve ( depending on which gas valve your heater uses) and trace with the other meter lead through the connections to the roll out switch, water pressure switch, both high limits,the thermostat and the on/off switch at some point you will lose your 570mv reading. That will be the control/safety/switch that is preventing the heater from firing.
Thanks again. I jumped all the connections since my multi meter wouldn't reach. None of them fired the heater. Jumping the TH terminals stil fired it up. So I started wiggling the wires to see if there was a loose connection. Seems like the connections to the rollout switch were a bit loose as the heater fired up when I moved them. We will see next week when I turn the heater on for the season, supposed to get close to freezing overnight the next few nightsThis should be the manual for your heater: https://www.poolsinc.com/pdf/raypak/raypak-digital-heater-product-manual.pdf Refer to the wiring diagram on page 28.
