| Symptom | Probable Cause | Suggested Action |
|---|---|---|
| EE0 Displayed On Control Board | EEPROM/Control Board Fault Or Communication Error | Power Cycle, Check Wiring, Replace Control Board |
| Intermittent Operation | Loose Connections Or Faulty Sensors | Tighten Wiring, Test Sensors, Replace Faulty Parts |
| No Ignition | Safety Lockouts Or Ignition Circuit Failure | Check Flame Sensor/Ignitor And Error History |
What The EE0 Error Code Means
The EE0 code on many Goodman furnaces generally points to a control board memory or electronic communication problem. EE codes often relate to the furnace’s electronic control module and its stored settings or internal diagnostics. EE0 can indicate a non-volatile memory (EEPROM) checksum error, firmware fault, or a failure to communicate with other control components.
Manufacturers sometimes label board-level faults with similar codes, so the exact meaning may vary by model. The furnace manual or the control board decal frequently lists the factory interpretation of the EE0 code for that unit.
Safety First: Precautions Before Troubleshooting
Working on gas furnaces involves shock and combustion risks. Always shut power to the furnace at the service switch and the breaker before inspecting internal components. Turn off the gas supply if any work involves burners, gas lines, or the ignition system.
If the homeowner is not comfortable or lacks electrical experience, calling a licensed HVAC technician is recommended. Incorrect repairs can create safety hazards and void warranties.
Initial Quick Checks
Before assuming a failed control board, perform simple checks that often resolve EE0-like symptoms. These steps are safe for most homeowners and can restore normal operation.
- Power Cycle The Furnace: Turn off the furnace at the breaker and service switch for 60 seconds, then restore power. This can clear transient EEPROM or firmware hiccups.
- Inspect The Display/LEDs: Note any other error codes or LED blink patterns, as they provide diagnostic clues.
- Check Thermostat And Wiring: Confirm thermostat calls for heat and that low-voltage wires are secure and undamaged.
- Examine Fuses: Look for blown control board fuses (often a 3A or 5A blade fuse) and replace with the correct type if blown.
Diagnostic Steps For Technically Minded Users
If initial checks fail, a more systematic approach helps isolate the fault. The following steps assume basic electrical testing skills and use of a multimeter.
1. Review Error History And Manual
Locate the furnace’s model and serial number and consult the owner’s manual or the schematic on the blower compartment door. Identify the EE0 description specific to the model to avoid misdiagnosis.
2. Verify Low-Voltage Power And Signals
Measure 24VAC supply at the control board terminals to ensure proper transformer output. Test thermostat wires for continuity and correct voltage when the thermostat calls for heat.
3. Inspect Wiring And Connectors
Look for loose connectors, corroded wires, or pinched cables. Re-seat multi-pin connectors on the control board and sensors, because poor connections can trigger communication errors including EE0.
4. Check Sensors And Ignition Components
Faulty flame sensors, pressure switches, or ignitors sometimes cause the control board to enter error states. Clean a flame sensor with steel wool and test pressure switch continuity during a call for heat.
5. Test The Control Board
If other components test normal, the control board is a likely culprit. Some boards provide diagnostic LED blink codes and a troubleshooting table. If the EEPROM has failed, the board may display EE0 repeatedly and fail to respond to resets.
Common Causes And Recommended Fixes
| Cause | How It Triggers EE0 | Recommended Fix |
|---|---|---|
| EEPROM Or Firmware Fault | Corruption Or Failure Of Non-Volatile Memory | Replace Control Board; Check For Updates From Manufacturer |
| Loose Or Damaged Wiring | Intermittent Communication Between Modules | Repair Or Replace Wiring; Re-seat Connectors |
| Failed Sensor (Flame, Pressure, Thermistor) | Invalid Or Missing Input Causes Board Error | Test And Replace Sensor |
| Blown Fuse On Control Board | Loss Of Power To Electronics | Replace Fuse And Address Underlying Cause |
| Transformer Or Power Issues | Low Or No 24VAC Supply | Repair/Replace Transformer Or Fix Power Source |
When To Replace The Control Board
Replacement is reasonable when diagnostics isolate the control board as the root cause, especially after verifying power, wiring, and sensors. Signs pointing to board replacement include persistent EE0 after resets, other components test correctly, and the board shows internal error indicators consistent with memory faults.
Before replacing, confirm the replacement board’s part number and any required configuration jumpers or dip switches. Some boards require dealer programming or matching serial numbers for factory settings.
Cost Estimates And Timeframes
Costs vary by model and region. Typical price ranges:
- Control Board Replacement: Parts $200–$600, labor $150–$400 depending on local rates.
- Sensor Replacement: Parts $20–$120, labor $80–$200.
- Transformer Replacement: Parts $30–$150, labor $100–$250.
Emergency service or same-day visits increase labor costs. For warranty-covered units, an authorized Goodman/Amana dealer may provide reduced or free repairs if the control board or components are under warranty.
Resetting The Furnace And Clearing EE0
A proper reset can sometimes clear transient errors, but persistent EE0 indicates a hardware fault. Safe reset steps:
- Turn off the furnace via the wall switch and the circuit breaker.
- Wait 60–90 seconds to allow capacitors to discharge and the control memory to clear volatile faults.
- Restore power and observe the control board LED pattern and display for changes.
If EE0 returns immediately or within a short time, proceed with the diagnostic steps above, or contact a professional.
Warranty, Replacement Parts, And OEM Advice
Check the furnace’s limited parts and heat exchanger warranties prior to repairs. Replacing an OEM control board with a non-OEM part may void the warranty and could affect safety interlocks.
When contacting Goodman/Amana support or an authorized dealer, provide the model and serial numbers, a photo of the control board sticker, and a clear description of the EE0 behavior. This information speeds accurate diagnosis and part matching.
Preventive Maintenance To Avoid EE0 And Related Failures
Routine preventive care reduces the chance of electronic faults causing EE0. Recommended maintenance items include:
- Annual professional tune-up to inspect electrical connections, sensors, and combustion components.
- Keeping the furnace area clean and dry to prevent corrosion and wiring damage.
- Replacing air filters regularly to prevent airflow problems that stress components.
- Addressing frequent power interruptions or voltage irregularities that can corrupt control electronics.
When To Call A Professional
Call a licensed HVAC technician if any of the following apply: persistent EE0 after resets, unfamiliarity with electrical diagnostics, visible gas leaks, or uncertainty about safe disassembly. Professionals have specialized tools, replacement boards, and access to official schematics.
Request a written estimate that lists labor, parts, and warranty coverage. For safety and compliance, ensure the technician is certified and licensed in the local jurisdiction.
Key Takeaways And Action Checklist
- EE0 Usually Relates To Control Board Or Communication Faults: Treat the control board as the likely problem after basic checks.
- Start With Safe, Simple Steps: Power cycle, check fuses, inspect wiring, and consult the manual.
- Perform Diagnostic Tests If Qualified: Verify 24VAC, sensors, and connectors before replacing the board.
- Replace The Board When Diagnostics Point To EEPROM Or Firmware Failure: Use OEM parts and verify warranty status.
- Call A Pro For Safety Or Uncertainty: Avoid DIY repairs involving gas or complex electronics if not experienced.
For homeowners searching “Goodman Furnace Ee0 Code”, following these steps helps pinpoint the issue and decide whether a DIY fix or professional service is appropriate. Accurate diagnosis avoids unnecessary costs and ensures safe, reliable furnace operation.
