Interestingly enough, I am fairly certain I am the "one report" mentioned in the CPSC recall. I had the experience in my own home and followed up with this letter to an engineer I had been discussing it with at Rheem.

ATTN: Harold C ......................RE: Model ROBF-112
Dear Mr. C, ..............................Serial : DR 172 M090700088

I thought you would be interested in a follow up to my previous attached letter after our telephone conversation.

A different serviceman from my oil company arrived today and saw the problem and fixed it all within the first 5 minutes without replacing parts. He had seen it before.

If you remember,
Thermostat calls for heat and the burner runs for 60 seconds approximately.
Burner shuts off for 2 seconds.
Blower starts and runs for 30 seconds.
Blower shuts off for 2 seconds

As it turns out, the installer put the two thermostat wires on the nearby relay directly bypassing the controller, so the burner would run until it reached the safety limit and then the fan would run until it cooled it down.

In all fairness, the mistake was not that hard to make and it may be more common than you think on systems without central air conditioning.

There are two spare terminals on the relay that match the color code and size of the thermostat wires and look like the right spot to put them, especially when the thermostat then starts the burner upon testing.

The actual terminals R& W, already have heavier gage wires on them and the thermostat wires need to be doubled up there. This appears this way on the wiring diagram but better labeling might be a good idea. In fact you may consider publishing a service bulletin on it. My unit ran half the winter this way and others may be similarly connected.


Thank you for your assistance,
Sal Castro, P.E.
