Problems with your Goodman thermostat can impact your whole HVAC system. Goodman thermostat troubleshooting may help you find a solution without calling a pro.
Goodman thermostat temperature doesn’t match room temp
Open your thermostat and dust it with canned air or a soft cloth. Your sensors may be dirty and unable to accurately read the temperature.
Check your air filters. You should replace them regularly. If yours is covered in thick dust, buy a new one and replace it.
Walk around your home and feel for drafts, especially near windows and doors. You may have an air leak. If you find one, seal it with weatherstripping.
If you can access your ductwork, check for damage, clogs, or holes at joints. Seal any holes with duct tape or sealant. If you can’t access your ductwork yourself, consider hiring a duct cleaning service. According to HomeAdvisor, duct cleaning costs about $376.
If none of these Goodman thermostat troubleshooting tips work, consider calling an HVAC expert to take a look.
Goodman thermostat is not connecting to HVAC systems
Check the power to your thermostat. If you’ve blown a fuse, replace it. Switch on any breaker that may have been tripped. If your thermostat takes batteries, change them.
If you can still interact with the thermostat, turn it to “heat” and “on.” Then try “cool” and “on.” You may be able to isolate the problem to a specific connection if one works and the other does not.
In many cases, this is an issue with the electrical connection to the thermostat. It can also be an issue with the wiring connecting the thermostat and your other HVAC equipment, like a Goodman furnace or air handler. In either scenario, you’ll want to contact an HVAC repair person for a professional fix.
