Possible Wrong Restrictor Plate Hole Size On 80% Tubular Furnaces Manufactured From Oct 2006 to Mar 2007
Type: Service Alert
Recall or Alert Date: 04-24-2007
Serial Number: YS-019 -07
Brands Affected: York
There was a process change in the fabrication of restrictor plates for 80% tubular furnaces starting in October 2006. As a result there is a small chance that some furnaces were assembled
with the wrong size restrictor plate vent hole. We have two confirmed cases to date. Actual number of defective units is expected to be very low. The effect of an undersized vent hole would be the same as a restricted vent; pressure switch not making or nuisance tripping. The possibility also exists for main limit or rollout nuisance tripping on long run cycles.
