How Do You Reset the Pressure Switch On A Goodman Furnace?

Resetting the pressure switch on a Goodman furnace is a task that can be completed in a few steps. However, it’s important to remember that working on a furnace can be dangerous if you’re not familiar with HVAC systems. If you’re not confident in performing these steps, it’s always safer to call a professional technician.

Here’s a general guide on how to reset the pressure switch on a Goodman furnace:

  1. Turn Off the Power: Before doing any work on your furnace, ensure that the power supply is completely turned off. This can typically be done at the main electrical panel or at a switch on the furnace itself.
  2. Locate the Pressure Switch: The pressure switch is usually a small, round component with wires connected to it. It is often found near the motor or the heat exchanger. The switch may have a rubber tube connected to it, which measures the pressure inside the heat exchanger.
  3. Inspect the Pressure Switch and Tubing: Before resetting, check the switch and tubing for any signs of damage or blockage. Sometimes, problems can be caused by a clogged tube or a faulty switch.
  4. Reset the Switch: If the switch has a reset button, press it. Not all models have a visible reset button, and for some, the reset process might involve simply removing and reattaching the wires or tubing.
  5. Check the Furnace’s Venting System: Sometimes, the issue with the pressure switch can be due to problems with the furnace’s venting system. Ensure that the venting system is clear of any blockages and that all vents are open and unobstructed.
  6. Turn the Power Back On: After you’ve completed these steps, turn the power back on and monitor the furnace. Check if the furnace is operating normally and whether the issue with the pressure switch has been resolved.
  7. Call for Professional Help if Needed: If the furnace still isn’t working correctly after you’ve attempted to reset the pressure switch, or if you’re unsure about any steps, it’s wise to call a qualified HVAC technician for help. They can diagnose and fix any issues safely and correctly.

Remember, safety is paramount. Don’t attempt any repairs you’re not comfortable with, and always refer to your furnace’s specific manual for guidance tailored to your model. Regular maintenance by a professional is also key to preventing issues with your furnace.
