Hello all - I am new to this forum and a guy who like to do all of his own repairs.
I have 2 issues with my 9 year old Raypak (Rheem) 406A heater atmospheric.
1) the heater will kick on and run properly for about 10-15 minutes, then the flames go off and the heater screen goes back to "SPK" and you can hear the igniter trying to light the flame. If you turn the system off and let it rest for about 5 minutes it will kick right back on, but will only run about 2-3 minutes before it does the same thing.
2) I have an Intellitouch i7 system. The heater use to connect to the system just fine. Now the heater controls will not let me connect to "REM". It will go there for about 2 seconds, but then goes back to onboard controls.
Any help with these two issues would be greatly appreciated...
