I've been searching the site with no luck, but would anybody have a tech sheet or ANY info on FPBS2777RF1? Its a frigidaire fench door/bottom mount, just out of warranty.
So the original complaint was warmer temps and a "high temp detected" light on display (verified when I got there). There was a good bit of frost build up on the evap, and the heater had continuity, so I assumed it was either the thermostat or Control board. I got continuity on the stat with my hair dryer on it, so I assumed it was bad (?). I'm fairly new to refrigeration, so please correct me if I'm wrong. Should the thermostat be closed when cold, open when hot (after the heater has defrosted the coils)? Doesnt it open somewhere between 40-90 faranheit?
Well, anyway that's I banked on and ordered the stat. I defrosted it and came back yesterday with the part. So this is what really made doubt my diagnosis... I tested the new stat at room temp and also with a hair dryer on it and it had continuity on it just like the original. Am I missing something? Again, I have very little experience with refrigeration, but I followed some tips online and according to what they were sayong the stat was bad...
So anyways coils were frosted up again, but it was at proper temp but still had that "high temp" error in the display. I went ahead and put in the stat but started second guessing myself which is why Im here! There's alot of knowledgable techs on here and you guys have saved my butt in the past so I thought Id run it by...
I guess I really need to know if all defrost thermostats are the same??? Any help is appreciated!
