I have a 15 year old Raypack 2100 Digital Natural gas heater. Body a little rusted but I have kept it in good shape by winter storage.
The unit is a 400,000 BTU model.
I cannot fire it up this season. I get an error code of PRS for a pressure problem.
I have replaced and tested a new pressure switch. Exact same model as the old one.
I get a "Call for Heat" code (CFH). The unit lights the pilot and then reads "PRS and service heater" with a fast click and code flashing.
The pilot lights for about 5 - 10 seconds and goes out. I can hear clicking of a relay or solenoid. CFH, HL1 and PRS willl flash.
Raypack support told me it was either the pressure switch, a blocked heater core or bad wires. I checked the wires to the P switch for continuity.
I completely cleaned my DE filter cartridge and basket. I have 14 pounds of pressure in the heater and filter. My returns run full power.
I also ran the pool in re-circulate mode in case the filter was the problem. I have a good gas flow to the switch.
I swapped out the heater tray with the gas valve assembly attached. I had 2 and have the same codes and issues with both.
The harness to the main board is clean and in good shape. I even replaced all the old wire connectors that were weathered.
I got a free estimate from a repair guy and he told me it was either the board with a bad relay or another bad gas valve. The Raypack guys think not.
I am out of options. Can anyone help?
Thanks in advance!
