Starting the Furnace
Starting your Goodman furnace is a straightforward process, but it’s important to follow the proper steps to ensure safe and efficient operation. First, locate the thermostat and make sure it’s set to the desired temperature. Turn on the power switch located on the furnace. You may hear a clicking sound as the ignition system engages. Observe the flame pattern; it should be stable and consistent. If the flame is erratic or flickering, it could indicate a problem with the gas supply or ignition system. If you notice any issues, turn off the furnace immediately and contact a qualified HVAC technician for assistance. Once the burner is ignited, the blower motor will start circulating warm air throughout your home. You should feel a noticeable increase in temperature within a short time. Always refer to your Goodman furnace manual for specific instructions regarding your model and any special features it may have.
Thermostat Settings
Proper thermostat settings play a crucial role in ensuring comfort and energy efficiency. Your Goodman furnace thermostat allows you to adjust the temperature according to your preferences. The thermostat’s settings will vary depending on the model, but most include options for setting the desired temperature, fan speed, and system mode. During the heating season, set the thermostat to “Heat” and adjust the temperature to your desired level. The furnace will automatically turn on when the room temperature falls below the set point and turn off when it reaches the set point. You can use the thermostat’s “Fan” setting to circulate air even when the furnace is not actively heating, which helps distribute air evenly throughout your home. Consider programming your thermostat with different temperatures for different times of the day to optimize comfort and energy savings. Consult your Goodman furnace manual for detailed instructions on your specific thermostat model and its features.
