View Full Version : Bryant Model 698B compressor shutdowns

We have a Bryant Heat Pump Model 698B (10 year parts and labor-compressor labor included) purchased in May of 2004 with a recurring problem: the compressor spontaneously shuts down in the summertime. The first time this happened was one year after the unit was installed. The dealer's tech told us the line voltage from the street was too high (249V) for the unit's rating of 208-220V. Our power company came out, took a reading and told us that the voltage was fine and any fluctuations were within normal parameters. The dealer then replaced the compressor, and we have had no more problems until three weeks ago. The technician came out and was unable to figure out why the compressor shut down this time, but said he read a Code 6; however, neither he nor the dealer can seem to figure out what this means. They tell us they are searching the Internet to try and figure this out! In the meantime, the only way we are able to get the unit running again is to flip our circuit breaker on, wait about 10 seconds, and then flip it back on again. This lasts for about 1 day. Any ideas?

Unfortunately, I am just an ignorant homeowner, and therefore don't know what you are referring to. I can tell you that when trying to decipher the tech's chicken scratch on the "Diagnosis/Solution" portion of the service receipt, it looks like he wrote "Board flashing Code 6. Reset Board. Ran Unit". The rest is undecipherable except the very last entry which read "Find out about Code 6".

Just in case anyone is on the edge of their seat wondering what happened....We finally had 2 techs come out who are trained in the HVAC side of things (according to them, the original tech is on the "plumbing side" ), and the flashing code 6 refers to the compressor. This was readily apparent when they went to our indoor unit, pulled off the manual that was taped to the unit, and read what the code meant. And this is what it took the dealer 3 weeks to still not figure out....
Bottom line - they determined that the unit was actually wired incorrectly at the factory, which was causing 390V to feed back into the unit, causing it to, thank goodness, shut down whenever it tried to bump up to the higher cooling level of our 2-level compressor. Who would've thought?
