3 Reasons Your Goodman Furnace Might Be Blinking Error Code 7

Your Goodman furnaces are the perfect addition to your home. They can keep you warm and cozy even on the coldest days. They’ll automatically switch on when it gets chilly in your house, so you don’t have to worry about shivering through your next arctic blast. Consequently, when something goes wrong with your furnace, it can feel like the absolute worst news in the world. You probably start stressing out over how much a new one will cost and what other expenses might be coming up as a result of this problem. Although these reactions are all completely understandable, there really isn’t anything to worry about when your furnace starts blinking error code 7. It might seem like a big concern at first glance, but there are often very simple explanations for why that light is flickering red and producing this code. Here are three reasons why this could be happening:

Your Furnace is Overloaded

When your furnace is overloaded, it’s having to work harder than it can physically handle. This can result in the motor burning out or the furnace simply breaking down entirely. If your furnace is overloaded, you’ll see error code 3. Unfortunately, there aren’t too many ways to avoid this problem. If you have a small house or a very large family, you’re going to want a furnace that has plenty of space to accommodate everyone. If you’re living in a big house with a lot of people, but you only have a mid-range furnace, that might be a sign that it’s time for an upgrade. Overloaded furnaces can also be caused by an improperly working thermostat. If it doesn’t have the right settings for your house, it might try to keep your house warmer than necessary. This can strain your furnace and cause it to work overtime. If a furnace is working too hard, it’s going to break down quicker than it might normally.

Something Is Blocking the Vent

There are usually two vents on a furnace. The first one is where the exhaust exits your home. The second one is where the air comes into the house. If there is something blocking the vent where the air comes in, like leaves or branches, your furnace will not be able to function properly. This causes your furnace to blink error code 7. Unfortunately, it’s not uncommon for leaves or other debris to build up in the vent. This is especially true if you live in an area that gets a lot of leaves or other debris that falls from trees. If you notice that your furnace is suddenly producing error code 7, you should definitely inspect the vent to see if there’s anything blocking it. If there is, you’ll need to remove it so that your furnace can start working correctly again.

The Filter is Full

The filter in your furnace is the thing that keeps all of the dust and other little particulates from being circulated throughout your house. It’s a very important part of your furnace and it needs to be clean at all times. If it gets too full, dust can start to build up on the interior of the furnace and clog holes in the filter. If the filter is completely clogged, it will produce error code 7. You should clean your filter once every two weeks or so to keep things flowing smoothly and to keep your furnace in good shape. If you’re noticing that your furnace is producing error code 7, you should clean the filter to see if that clears up the problem.

Your Thermostat Isn’t Setup Correctly

A thermostat is a pretty sophisticated device. It can measure the temperature in your house and decide when it’s appropriate to turn on the furnace. Unfortunately, these devices are pretty finicky. They can be a little temperamental at times and require some fine-tuning. If you’ve recently changed the temperature settings on your thermostat and you’ve forgotten to adjust the furnace settings, it might be producing error code 7. If you’ve recently changed the settings on your thermostat, it’s a good idea to go back and check your furnace settings to make sure they’re correct. If they aren’t, your furnace won’t know when to turn on or off. When you’re adjusting the settings, it’s important to make sure they’re accurate. It’s best to have someone come out and actually check the temperature in your house with a thermometer. This makes it a lot easier to set the furnace correctly.

There’s a Problem With Your Sensor

A lot of newer furnaces have sensors that measure the temperature in your home. These sensors are what allow your furnace to know when it’s necessary to turn on. If there’s a problem with one of these sensors, your furnace might start to blink error code 7. The good news is that this problem is often easy to resolve. The only way to find out if your sensor is causing the problem is to replace it with a new one. If you’re not sure how to do that, it’s a good idea to call an HVAC technician. Having a professional come out and take a look at your furnace can help you determine the cause of the problem. A professional can replace your sensor in a few minutes and can let you know if this is the problem.

Goodman Furnace Won’t Turn On

If your furnace won’t turn on, it could be for one of two reasons. First, your circuit breaker could be tripped. A lot of people don’t know that a circuit breaker can overheat if it’s being forced to work too hard. If you have more than a few high-energy appliances plugged in, the circuit breaker can trip. Tripped circuit breakers will turn off all power to the house. If you have a very large house or a house with a lot of power-consuming appliances, you might want to get a circuit breaker that’s a little bit bigger than the recommended size. If your circuit breaker is tripped and you reset it, your furnace should turn on again.

Conclusion

There are a lot of reasons why your furnace might be blinking error code 7. Unfortunately, sometimes you’re just going to have to bite the bullet and call a professional to come out and take a look at your furnace. A professional will be able to tell you exactly what’s causing the problem and can let you know whether it’s something you can fix yourself or whether you’ll need to replace the furnace entirely. When your furnace starts blinking error code 7, don’t panic. There are likely a few simple solutions that can help you get your furnace working properly again.
