Question about Heating & Cooling

Open Question

We have a Rheem Pool heater 009977 model #P-M406A-EP-C, we can not get it to light. We turn it on it tries to light (goes to CFH a couple of times) then ROL comes up with Service flashing in the upper right corner. It's for a spa and is a couple of years old.

SOURCE: I have a Rheem raypack pool and spa heater. I have

Error Code ROL is "HEAT ROLL-OUT SAFETY SWITCH OPEN". The heater is equipped with a cutoff device to prevent flame roll-out in the event the heat exchanger becomes blocked. This is either a "manual reset", or "Single-use" type fusible link/thermal fuse, that must be replaced or reset after any over temperature conditions have been fixed. Excessive restriction in the heat exchanger flue passage may cause the switch to disable the heater. I don't know your exact model so I'm just generalizing. If you reset or replace the switch, and it trips/burns out again, then you need to address what is causing it. make sure the heater is cleaned out well and no debris is blocking the flue. I fthis doesn't help you can always try calling Raypak Service department at (805) 278-5300.

ROL code means Rollout.
This heater used a one time use switch in the cabinet on the left hand side.
The switch will look like a ceramic oval disk about 1.5" in diameter. It will have two wires coming from it.
This switch is one time use because it mean your heater is getting a bad burn. This could be happening due to:

1. High wind situation (could be random)
2. Incorrect gas supply
3. Incorrect venting (if indoor)
4. Obstruction on top of the burner tray.

There was a recall on the refractory kit with some of these models, causing the fire walls to crack off and fall on top of the burner tray. Thus causing the flames to rise too high inside the cabinet and therefor trip the rollout switch. The timeline for the recall matches your heaters date.

E-mail me if you need more help.

Rheem pool heater, M406A, display has failed. It is only partially readable and has a dark spot inside it. Is the replacement part the PC board/controller? Is this a job for a savvy homeowner or call


The display is part of the pc board and it is very easy to replace. It is also fairly expensive part just to read the temp(around $400.00). If the heater works fine except for the display you can get by. Hit the up arrow button about thirty times this will ensure you have max'ed out the temperature at 104 degrees. From there with the down arrow you can count down to the desired temp. The mode button should work normally to turn the heater on or off as desired. This is obviously not the repair but it will buy time until you are prepared to replace it or have a technician out for another call.

Rheem digital gas pool heater fan code


The Fan code would indicate a problem with the combustion air blower. The is a pressure switch to indicate there is sufficent combustion air, and if not then unit shuts down. Either the fan isn't running, or there is an obsturction in the fan or exhaust piping, preventing enough air flow.
cfh would be call for heat, which would be a normal display when water temp is below setpoint
See the link below for a manual. Once you open the page look on lower right side for documents, then install manual

I have a Rheem Raypack pool heater and cannot locate my manual. The model is pr266a-ep-c. Is there a way to get the manual?


If you run a search for Rheem or RayPak the site should bring you to a menu that will have most manuals.
www.raypak.com/uploads/6000.52AG.pdf

This link may help but I think it goes to an older heater, but it will give you a start.
