Technical Bulletin: Goodman Inducer Elbow & Pressure Switch Issues

We have identified a potential cause for intermittent pressure switch trip-outs on certain Goodman units. If you are encountering these issues in the field, please review the following updates regarding the inducer elbow assembly.

The Issue: Improper Drainage

Standard inducer boots may allow moisture to bypass the primary drain path, causing water to recirculate into the inducer housing. This accumulation often leads to pressure switch fluctuations and system lockouts.

The Solution: New Inducer Elbow

A redesigned inducer elbow is now available. This updated component is engineered to:

• Improve Drainage: Directs condensate efficiently to the actual drain.

• Prevent Recirculation: Eliminates "bypass" moisture that would otherwise return to the inducer.

Field Requirements & Best Practices

While the new elbow resolves internal drainage issues, it does not compensate for poor external venting. Please ensure the following standards are met on every call:

• Verify Venting: Confirm all venting configurations strictly adhere to the installation manual.

• Maintain Slope: The absolute minimum slope for vent piping is 1/4" per foot back toward the unit.

• Go Beyond Minimums: If the installation allows for a steeper pitch, implement it. A more aggressive slope is always preferred to ensure proper drainage.
