Reviews
Featured positive reviews:
Works great. Even better than the original when it was new. This replaces the old model -001, fits perfectly and runs like a charm. this one delays the start of the blower until the coil is chilled. My other one came on with the compressor and blew hot air for a while. I'll bet I save good money with this one!
Original Control Board failed after 25 years. Replacement 40403-003 has wiring in the same positions and terminals clearly marked. A 20 minute swap. Board works perfectly!
Fast processing and shipping. Charges very reasonable. Exactly as ordered, no problems, everything went very smoothly. the piece fit exactly and was a snap to install.
