Goodman, Amana, Daikin GMVM96 error code b0
Blower motor not running
Goodman is the platform name, and your unit may not say it
Amana AMVM96 / ACVM96, Daikin GMVM96 platform are the same board with a different badge, so this page covers all of them. The fault, the checks and the parts are identical, which is why there is one page rather than one per brand.
Quick answer
On Goodman GMVM96 (2010s), b0 is a fault. It means blower motor not running. A first thing to check: Failed blower capacitor.
- Applies to
- Goodman GMVM96
- Goodman and Amana GMVM96, GMVM97, GCVM96 alphanumeric codes · Furnace · 2010s
- Type of code
- Fault
- Urgency: Needs attention soon
- First safe check
- Push the blower wheel gently by hand with the power off. It should spin freely. If it is gritty or locked, the motor is going.
What b0 means on this model
The control has commanded the blower and nothing happened. Either the motor gets no power, the capacitor is dead, the motor is seized, or a control board output has failed. On a gas furnace this usually shows up as no heat, because the furnace will not fire without airflow.
Symptoms you will notice
- No air moving from any register
- Furnace will not fire at all
- You hear the inducer but never the blower
- Code appears a few seconds after the call for heat
Common causes
The code tells you what the control detected, not which part failed. These are the causes we see most often, roughly in order of likelihood:
- Failed blower capacitor
- Seized or failed blower motor
- Loose or open blower wiring or connector
- Failed control board output
- Blower wheel jammed against the cabinet
- Open thermal limiter on some older units
What you can safely check
These are homeowner-level checks. None of them need you to open a live electrical compartment or work on gas.
- Push the blower wheel gently by hand with the power off. It should spin freely. If it is gritty or locked, the motor is going.
- Look at the capacitor. A bulging or scorched can is a failed capacitor.
- Check the blower connector for a loose plug.
Do not do these
- ×Do not touch the blower wheel with the power on. It can start without warning.
- ×Do not repeatedly reset expecting a seized motor to free itself.
When to call a technician
Book a technician, do not keep resetting it
This fault will not clear on its own. Every power cycle gives the control one more failed attempt, and repeated attempts are what turn a cheap part replacement into a seized or contaminated system.
- This is a fuel-burning appliance, so treat anything involving a burner, gas valve or flue as technician work. If you smell gas at any point, leave the property and call the gas utility from outside rather than continuing to diagnose.
- If the appliance has stopped mid-cycle, is making a noise you have not heard before, or smells burnt, stop reading here and call. Those are symptoms of something the fault code does not describe well enough.
A capacitor swap is straightforward. A blower motor on a sealed combustion furnace is technician work.
What it costs to fix
Parts
Capacitor $15 to $40. Blower motor $250 to $500. Control board $250 to $500.
Labor
Three to five hours to replace a blower motor on a gas furnace, because the burners and gas train have to come out for access.
DIY or technician
A capacitor swap is straightforward. A blower motor on a sealed combustion furnace is technician work.
