Carlin 42230 Oil Primary Control 4223002S

I bought this controller to replace an old, tired Carlin 42230-02A. I was having trouble with intermittent lockouts. After some research into the problem I decided to try a new controller. It starts up perfectly and the diagnostic LEDs help to show it working correctly. In the process of replacing this controller, I found that a numb-skull had wired the old one (many years ago) incorrectly, that is igniter and motor together. Grrrrrr. This is an intermittent ignition. If you want something done right and you have some basic knowledge, do it yourself.

The flame sense function stopped working on our old controller. The model number matched the one on our burner, and someone else was nice enough to say that they got this to work with their Lanair. I'm always worried that there is going to be something different that I'm not going to realize until it is too late, but this worked out just fine. Hopefully it works for over 10 years like the last one did.

Took a little bit of thinking to replace the older control module, but works perfect.

WORKS GREAT AND CHEAPER THAN BUYING IT FROM THE ELECTRICIAN

It worked for what I needed it for.

We diagnosed, ordered and installed this part, all went well

As described and good price

Works great , the new version has a green led showing flame sense - good or bad . Good improvement
