Amana Furnace E06 Error Code - Causes & Fix

Amana Furnace E06 Error Code — What It Means

The E06 error on Amana furnaces indicates a blower motor or blower circuit fault. The control board has detected that the blower motor is not responding correctly, is drawing abnormal current, or has stopped due to an open or short circuit. This fault is part of the Amana/Goodman diagnostic code family and typically points to a failed ECM blower motor module, a damaged wiring harness between the board and motor, or less commonly a control board issue.

The blower motor moves heated air through your ductwork, so when this fault occurs the furnace will usually shut down or fail to complete its heating cycle. Field reports also link this code to abnormal incoming line voltage, overheating from restricted airflow, or a defective memory chip on the control board itself.

Common Causes

• Failed ECM blower motor or module Internal electronics in the ECM motor have failed and the motor no longer responds to control signals from the board.
• Loose or damaged wiring between control board and blower Connectors at the board or motor have worked loose, or the harness has been damaged by heat or vibration.
• Incorrect or unstable line voltage Supply voltage to the furnace is outside specification, has reversed polarity, or the ground connection is faulty.
• Restricted airflow causing motor overheating A dirty filter, blocked return, undersized ductwork, or excessive static pressure forces the blower to overheat and trip the fault.
• Faulty integrated furnace control board The control board is not sending correct commands to the blower or has a memory chip fault that triggers false error codes.

Step-by-Step Fix

1. Turn off power at the furnace disconnect and the circuit breaker, then wait two minutes for the control board to clear before restoring power and observing the LED fault display to confirm the code.
2. Check and replace the air filter, inspect the return and supply grilles for blockages, and verify that all registers are open to rule out restricted airflow as a trigger.
3. Measure incoming line voltage at the furnace with a multimeter to confirm it is within the label specification (typically 115 VAC +/- 10%), verify correct polarity, and inspect the ground connection.
4. Inspect blower compartment wiring by removing the blower access panel, checking the harness and connectors at both the control board and the ECM motor for looseness, corrosion, or heat damage, and reseating all connections.
5. Test the ECM blower motor by observing whether it attempts to spin during a call for heat, listening for unusual noise, and checking for visible signs of overheating or a burnt smell at the motor module.
6. Isolate the control board by disconnecting the blower motor harness from the board and using a multimeter to check for short circuits to ground on the motor side, then reconnect and cycle power to see if the fault clears.
7. Replace the defective component after diagnostics confirm whether the ECM motor module or control board is at fault, then restore airflow conditions and run a full heating cycle to verify the error does not return.

Parts Often Needed

When to Call a Pro

Call a licensed HVAC technician if you are not comfortable working with line voltage, if you cannot safely access the blower compartment, or if basic checks of power and airflow do not resolve the fault. Diagnosing ECM motor control signals and confirming whether the motor module or control board has failed requires specialized tools and knowledge of the Amana/Goodman control architecture. A technician will also measure duct static pressure and verify that your system airflow matches design specifications, which prevents recurring blower faults after repair.
