Carrier furnace troubleshoot. Have you recently discovered your Carrier furnace isn’t working properly? It might panic you at first, but don’t worry.
Identifying issues with furnaces can be tricky, but here are some troubleshooting tips to help you diagnose the problem.
Once you discover what the problem is, there are methods or tips that can be handled quickly for a quick resolution- or alternatively, you may choose to hire a professional to perform them for you!

Here we will discuss some common issues and solutions for Carrier furnace troubleshooting.
Loud & Noisy Operation
The furnace wheel blows air through the home, and it is attached to a motor.
If the wheel is rattling on the engine, it may get damaged. Turn off the power and tighten any loose bolts to make sure it runs smoothly.
Inspect for any damage or corrosion before turning your furnace back on in case there are any problems with its functionality before calling a professional to come to fix or change the whole unit if necessary!
Over time, the fan belt becomes worn and loose. If your belt is worn and loose, first check to see if the mountings are still secure. Support them with a wedge of wood or shims if they are no longer tight against the motor shaft.
Replace the mounting bolts that have become loose with new bolts (anyone who knows anything about plumbing will be able to tell you where these bolts likely are hiding). Take this opportunity to replace any worn belts that show up while you are at it as well!
Stop After Few Minutes
A furnace’s flame sensor is what activates the furnace in order to light a gas valve in order to burn propane gas when it detects a live flame.
If a faulty flame sensor isn’t able to detect the presence of a fire or an improperly operating flame,
The furnace may not ignite the gas and may sound like an error beep from its thermostat control panel. When this happens, it’s important for you to have your heating system serviced immediately.
The control board in the furnace is essentially a traffic cop directing power flow to everything in it. If the control board malfunctions, it might not send voltage to its ignition system, and so the furnace shuts off after a few minutes.
Issue In Heating
An igniter is a part that lights the gas burner on a furnace. If an igniter becomes cracked or stops making contact, your heating system won’t work right. You can check for cracks by removing the old igniter and inspecting it.
If there are cracks, replace the igniter. If no cracks are found, touch a multimeter’s probes to lead from the new and old igniters.
If no continuity is shown, replace the new igniter with another one from the manufacturer of your furnace. If the flame sensor is faulty or dirty, it can break down and stop detecting the presence of a flame.
The control board will then shut off the gas valve to guard against a furnace fire, which might occur if there were no open flames present, to maintain an even heating temperature within the circulation system.
Blower Continuously Runs
There is a control board in this furnace that regulates the voltage to each component through relays.
If a relay is faulty and opens while it is supposed to be closed, it will disconnect the power that would be going to a connected component (like a blower motor) instead of letting it pass through to where it would otherwise go.
If the control board or any of its relays are malfunctioning, they will need to be replaced so as not to overheat other components or cause damage when in use.
The wall thermostat has two electrical contacts. The one for the blower motor determines whether power is supplied to it and when this contact gets stuck closed, the voltage will run continuously to the blower motor causing the motor to run continuously.
If you do get a reading in the off position, then your thermostat will need replacing as it’s faulty.
Blower Not Operating
Maintaining the efficiency of your equipment relies heavily on the blower.
The primary purpose of the blower is to send cooled air into the evaporator coil, which then travels through the system and gets ready for its next phase: being distributed throughout the room.
When the fan or motor overheats or fails to run at all, test it with a multimeter to see if the capacitor has failed.
The capacitor should be replaced if it has bulges or leaks. The way to test a capacitor with a multimeter is by taking off one of the capacitor’s wires and placing the leads of your meter on them.
