Goodman Furnace Pressure Switch Malfunction: Symptoms And Troubleshooting
When a Goodman furnace’s pressure switch gets stuck open, it’s a common malfunction that can leave your furnace inoperable. The switch detects air pressure in the flue pipe and turns off the furnace when it drops too low. A stuck-open switch prevents the furnace from starting or running, as it doesn’t sense the necessary pressure. To troubleshoot, check the pressure switch hose for leaks or clogs, inspect the switch terminals for loose connections, and test the switch with a multimeter. If the switch is faulty, replace it to restore proper furnace operation.
Common Furnace Malfunctions with High Closeness Scores
Let’s face it, when your furnace starts acting up, it’s like the Grinch trying to ruin your cozy winter wonderland. But don’t worry, just like the Whos fighting back with their Christmas cheer, we’re here to help you understand and fix those pesky furnace malfunctions.
Furnaces have a bunch of components that work together to keep your home warm and snuggly. But just like any hardworking team, sometimes players get injured or start slacking off. These “common malfunctions” are like the high-score players in the furnace malfunction league, with closeness scores of 10, 9, and 8, meaning they’re frequently giving homeowners a headache.
10-Score Superstar: Pressure Switch
This little switch is in charge of checking the air pressure inside your furnace. If it’s too high or too low, it flips the switch to stop the furnace from overheating or underperforming. But sometimes, this trusty switch gets a little wonky and needs a checkup.
9-Score MVP: Draft Inducer Motor
Think of the draft inducer motor as the vacuum cleaner of your furnace. It sucks out the exhaust gases and brings in fresh air for the combustion process. But if it’s clogged up or malfunctions, you might start smelling something funky or notice your furnace not heating as well.
8-Score Contender: Vent System
The vent system is like the highway for your furnace’s exhaust gases. If there’s a blockage in the vent pipe or chimney, the gases can’t escape properly and can cause problems. It’s like trying to drive down a road with a giant traffic jam – not fun for anyone!

Pressure Switch Problems
A faulty pressure switch can prevent your furnace from starting or cause it to shut off prematurely. Here’s how to tackle this issue:
- Check for power. Use a multimeter to ensure that the pressure switch is getting power.
- Inspect the pressure switch and hose. Look for any visible damage or obstructions. Also, check the hose for leaks or cracks.
- Test the pressure switch. Disconnect the hose from the switch and blow into the port. If you hear a “click,” the switch is working properly.

Pressure Switch Woes: Troubleshooting Your Furnace’s Silent Sentinel
Hey there, fellow homeowners! If your furnace has been acting up, don’t fret. You’re not alone in the battle against furnace malfunctions. Today, we’re diving into the mysterious world of pressure switches and how to handle their pesky issues.
What’s a Pressure Switch, You Ask?
Think of the pressure switch as the furnace’s watchful eye, keeping an eagle eye on airflow. When air pressure drops or rises too much, it sounds the alarm, shutting down your furnace to prevent any potential disasters.
Checking for Power: The Path to the Pulse
Step one in our troubleshooting adventure is to check if there’s power flowing to the pressure switch. Grab a multimeter and test the voltage across the switch terminals. If it’s not getting enough juice, you might need to call in our trusty electrician friends.
Inspecting the Switch and Hose: A Close-Up Examination
Next, it’s time to give the pressure switch and its connected hose a thorough inspection. Look for any signs of damage, cracks, or loose connections. Sometimes, a simple cleaning of the switch or replacing the hose can work wonders.
Testing the Pressure Switch: The Moment of Truth
With the switch disconnected, let’s test its functionality. Use a vacuum cleaner to create a vacuum on the hose and observe the switch’s response. A working switch should close the circuit as the vacuum increases.
Cleaning or Replacing: The Final Reckoning
If cleaning doesn’t solve the problem, it might be time to replace the pressure switch. Look for a switch with the same specs as your current one. Disconnect the old switch and replace it with the new one. Remember, this task may require some electrical expertise, so if you’re not comfortable, call a pro.
Draft Inducer Motor and Vent System Issues: Fixing Your Furnace’s Breathing Problems
When your furnace starts acting up, it’s like having a sick house pet – you can’t help but feel a little panicked. But don’t fret! Sometimes, the problem is as simple as a blocked vent or a sluggish draft inducer motor.
Check for Blockages
Imagine your furnace is trying to breathe through a clogged straw. That’s what happens when your vent system is blocked. So, grab a flashlight and start exploring! Check for any obstructions like dust bunnies, pet hair, or even a forgotten sock in your ductwork.
Clear Obstructions from the Vent System
If you find any blockages, don’t be afraid to get your hands dirty. Carefully remove the obstruction and vacuum up any debris. It’s like giving your furnace a deep breath of fresh air!
Replace the Draft Inducer Motor
If blockages aren’t the issue, it’s time to check the draft inducer motor. This little powerhouse is responsible for sucking exhaust gases out of your home and bringing in fresh air for combustion. If it’s not working properly, your furnace will struggle to produce heat.
Replacing the draft inducer motor is a bit more involved, but it’s still doable for a determined DIYer. Just be sure to disconnect the power and gas supply before you start tinkering. Oh, and remember to consult your furnace manual for specific instructions.
