There is nothing more frustrating than coming home to a freezing house because your furnace is not working. In this article we’ll discuss when to call a professional, how you can save some money by diagnosing the issue and common furnace issues you might be having. If you’re experiencing trouble with your Goodman furnace, this article should help you to troubleshoot the issue.
Professionals to the Rescue For Goodman Troubleshooting
Generally speaking it is a good idea to call a professional for HVAC help. Often homeowners can make problems worse rather than better simply because they are not as familiar with the system and can damage it without knowing. With this in mind, there are a few things you can do to troubleshoot your problem. If you can at least narrow down the issue when you call a licensed professional you can save some money by having the problem diagnosed for them.
Possible Problems With Your Goodman Furnace
Important Note: Before troubleshooting or working with any HVAC system, be sure to turn off all electrical power and Gas to the system.
- Furnace Doesn’t Ignite the Gas
If your igniter doesn’t glow after the draft inducer runs and produces a hissing sound, most likely your inducer has gone out. Take a look at the igniter and inspect it for cracks. Don’t touch the igniter with your bare hands however. If you don’t see a crack it’s possible that the problem could be a control board problem or an issue with the rollout switch.
- Draft Inducer Won’t Start
If the draft inducer doesn’t start (you don’t hear a swooshing sound after it being on for 30 seconds to a minute) there is the possibility that your control board may be the issue. However, it could be a less costly item so it makes sense to check for other issues. Pressure and limit switches could be the culprits. Pressure and limit switches are there for your safety so it’s best to have these items tested by someone who is experienced with electrical equipment.
- Igniter Stops Too Soon
There are many causes for this issue. Your thermostat may have an improper heat anticipator setting. Another cause could be too much gas pressure – if this is the case, your furnace will make a very loud noise when running, much like a commercial airplane. If you have too much gas pressure it will cause your furnace to run too hot and it will shut itself off. A qualified HVAC technician needs to adjust this.
If you’re unable to troubleshoot your furnace, sometimes a specialist can give you HVAC help over the phone. Simply find your local professional and give them a call and describe your situation. If they can’t get you up and running they can come out and fully diagnose the issue and you’re house will be back to a comfortable temperature before you know it.
