Maytag Condensation and Corrosion

Furnace cabinet sweats or shows rust and corrosion, especially on high-efficiency models.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Improper condensate drainage, Low return air temperature, Undersized return duct, Leaking vent joints

Safety: Turn off power before inspecting internal components.

Steps to check:

Check condensate system: Ensure the condensate trap and drain are clear and not leaking onto the cabinet.
Inspect vent joints: Look for water stains around PVC vent joints indicating leaks.
Improve airflow: Make sure return ducts are not undersized or blocked, which can cause low surface temperatures and condensation.

When to call a technician: Persistent condensation or visible rust on the heat exchanger or burners should be evaluated professionally.
