Common Goodman Gas Furnace Issues

Goodman gas furnaces are known for their reliability. Yet, they can face common issues. Knowing these can help you troubleshoot quickly. This section covers two frequent problems: Ignition Failures and Thermostat Malfunctions.

Ignition Failures

Ignition failures are common in gas furnaces. They often happen due to a dirty ignitor. Clean the ignitor with a soft brush. If that doesn’t work, it may need replacement. Another cause can be a faulty flame sensor. Clean the flame sensor gently. If the problem persists, consult a technician. A malfunctioning control board can also cause ignition failures. This part might need professional inspection.

Thermostat Malfunctions

A malfunctioning thermostat can make your furnace act up. First, check if the thermostat has power. Replace the batteries if needed. Make sure the thermostat is set to “heat.” A dirty thermostat sensor can also cause issues. Clean the sensor with a soft cloth. Verify that the thermostat is correctly calibrated. If it’s not, you may need to recalibrate it. Incorrect wiring can also cause problems. Ensure all wires are properly connected. Sometimes, replacing the thermostat is the best solution.

Pre-troubleshooting Safety Tips

Before diving into troubleshooting your Goodman gas furnace, prioritize safety. Following these pre-troubleshooting safety tips ensures a safe environment. Simple steps can prevent accidents.

Power Shutdown

Always start by shutting down the power. Locate the furnace’s power switch. Turn it off to cut electricity supply. This prevents electric shocks and other hazards.

Next, switch off the circuit breaker. Find the breaker panel and identify the furnace switch. Flip it to the off position. This ensures no power flows to the furnace.

Gas Supply Check

After ensuring the power is off, check the gas supply. Locate the gas valve near the furnace. Turn it to the off position. This prevents gas leaks and potential explosions.

Ensure there are no gas smells in the area. Use your nose to detect any leaks. If you smell gas, do not proceed. Contact a professional immediately.

Action	Details
Power Shutdown	Turn off power switch and circuit breaker.
Gas Supply Check	Turn off gas valve and check for leaks.

Following these steps ensures a safe troubleshooting process. Always prioritize safety first.
