White-Rodgers Two-Stage Gas Valves (Amana Part #’s C6476906 and C6476909)
Type: Service Alert
Recall or Alert Date: 03-11-2003
Serial Number: GF-157
Brands Affected: Amana
Amana has received field complaints of nuisance lockouts on 40" 80% and 90% two-stage gas furnaces (Models GUIS, GCIS, GUIV, GUVA, GCVA and GUSA). The problem being reported is a steady on LED fault code, which would tend to indicate an internal ignition control board failure.
Our investigation has determined this complaint to be due to a cracked or loose connector terminal on the PC Board located inside the gas valve. This problem was found to be created when too much force is applied to the wiring harness connector as it is being connected to the gas valve causing the connector terminals to break the solder on the backside of the PC board. This issue affects only two-stage gas valves manufactured with serial date codes prior to 0215. Refer to the following figure for locating the date code on the gas valve.Affected Products:
