Goodman · Furnace

Eb3 Blower motor running in power, temperature or speed limit

Medium severity Goodman/Amana *MVC96 (34.5 in. chassis)

What the control is telling you

The motor is limiting itself, so airflow is lower than expected and the furnace runs with reduced performance.

Applies to: GMVC96, GCVC96, AMVC96, ACVC96 (*BA, ComfortBridge)

Likely causes

  • Dirty filter
  • Restrictive or undersized ductwork
  • High ambient temperature

Test and repair steps

  1. Turn off power before touching wiring or the board.
  2. Check the filter. Clean or replace it.
  3. Check ducts for blockage and make sure every register is fully open.
  4. Check duct size for the system and correct it if too small.
