Pressure Switch Nuisance Tripping on Amana® brand 90% ACV90* Counterflow Model Furnaces
Type: Service Alert
Recall or Alert Date: 01-20-2005
Serial Number: GF-174
Brands Affected: Amana
We have had a few reports of nuisance pressure switch tripping on Amana® brand 90% (ACV9070CXA, ACV90905DXA*) counterflow model furnaces.
Our investigation of the issue has determined the problem to be due to length of the pressure switch hose from the ID Blower to ID Blower Pressure Switch sagging. In order to address this issue, we reduced the pressure switch hose length to prevent sagging, which could trap moisture in the hose and cause nuisance tripping of the pressure switch.Affected Products:
