SOURCE: I have a Raypak heater for my pool and spa. The

The roll out safety switch has gone bad. This is a wax switch that melts and opens when flame comes out of the box and up the front of the cabinet. What causes this is a sooted heat exchanger, being adjacent to a tall wall (As explained in your book), broken firewall tile. The switch itself is a short black piece in the wire running across the bottom front of the heater. The new one will have a loose black covering and when it gets hot it will shrink and get tight. It will just plug into the wire and is very inexpensive. It's job is to protect the rest of the components in the cabinet.
Depending on the problem it can get rather in depth and is usually something I would recommend you get a professional to look at. Some of it can be complicated some of it is a fire hazard. You can try a new roll out switch first to see if this was a fluke. So you could fix it for $20.00 or you could be throwing $20.00 away. Quite often it's worth a try. Good luck.

Could be several things. The heater should still be under warrantee. Have RayPak send a tech over, any DIY will void the warrantee.

My raypac 2100 was working fine, recently replaced control pad. Today set heater to 90 it heated to 89 then pad read "off". Pad would not respond after that. Turned breaker off then on and error...


The EOL code means End Of Line. It means the heater has given up trying to run. There are a number of problems that could cause this issue. There could be no gas pressure, a defective gas valve, or something wrong with the control board, etc. To determine exactly what is wrong a person qualified to diagnose the problem will need to follow a diagnostics document from Paypak or call Paypak's technical support line. If you have a volt/ohm meter and have some debugging experience you might convince a tech support person to help you diagnose what the problem is. If you are not successful with that idea then you will need to find a pool equipment professional to do the job. I hope this helps.

Raypak pool heater - error code is "FAN"


In models older than 07-07 it typically indicates a loss of the pilot light.
In models newer than 07-07 it is probably the air switch not being activated, or it has just failed. Check air switch tubing for secure connections.

Raypak 2100 pool heater won't heat, PRS and HL2 error codes.


Well, I replaced the pressure switch with no joy. I tried all 5 levels of pressure 1-5 and every wiring combination. Finally, I returned the new $70 pressure switch and took the 2 wires and tied them together (jumped them). Here's the only downside...If you run your pump in backwash, recirc, waste, or any mode that would cause water to bypass the heater it MUST BE OFF. Otherwise, let it ride. It's working great and I hope to go into October weather permitting.

Raypak RP2100 pool heater set temperature stuck on 50 degrees


Could be spider webs in the orfices, which would allow the burners not to light.
Could also be a bad thermostat or pressure switch.

Pool heater will not work


Eol is a manufacturers code meaning End Of The Line. I have never seen this displayed on any malfunctioning heater that I've serviced. Try shutting down the power to unit and resetting the board.
