Note: This guide covers the most common problems, particularly those most property owners can easily consult no tools or fundamental tools such as screwdrivers and a multimeter.
1. The Furnace Won't Start
If nothing takes place when the thermostat is set above the house's existing temperature, the most likely causes are these:
- The breaker is off, and if the circuit continues to journey after it is turned back on, there is likely a circuitry short in the heater
- The thermostat isn't set to "heat," which is simple to inspect and treat
- The thermostat isn't working, and this is sometimes caused by a wire coming loose, so inspect the electrical wiring connections
- The thermostat needs fresh batteries, if battery-powered, or it is bad and need to be replaced, a concern that can be identified using an electrical multimeter that shows if a circuit is total
- The filter is filthy and need to be changed or cleaned, a problem that is particularly true on more recent heating systems that are geared up to close down if the filter isn't permitting sufficient air circulation, a condition that can trigger major mechanical failure
- The furnace's primary circuit board/control board is bad, a concern that can be identified by a HVAC professional is absolutely nothing else resolves the problem
2. Heater Blowing Cold Air
If the heater won't produce heat, you can check to see if it is getting power by moving the fan switch from the "Vehicle" position to the "On" position. If the fan comes on, then the heating system is getting power. The likely issues then are:
- The gas is switched off, so examine the gas cock near the heater to ensure it is parallel to the gas line
- The gas control valve isn't opening and should be changed
- The ignitor is stopping working and should be replaced
- The draft motor isn't functioning or the fresh-air intake is obstructed, possibly by snow or debris, and requires to be cleared
3. The Draft Motor Runs, Heater Won't Start
The draft motor is also called the inducer motor. It pulls hot combustion gases through the heater and out the exhaust stack. If it begins and after that the heater closes down, the cause might be:
- The motor or the board that manages it has actually stopped working and need to be changed
- A blocked air consumption or blocked exhaust chimney (snow, particles and bird's nests prevail causes) need to be cleared
- Among the problems discussed above with gas, gas valve and ignitor need to be dealt with
4. The Draft Motor Won't Start
The problem, in this case, is either that the motor is bad or the capacitor that supports it is bad. This video will help you in fixing draft motor problems and what is causing them.
5. The Flame Begins, but the Heater Shuts Down
If the burner starts making heat but soon turns off without warming your house, the flame sensor isn't working. If the sensor has deterioration on it, sanding it might work, though replacing it is a longer-lasting fix.
6. The Blower Will Not Shut Off
If the blower motor runs all the time, there are three typical problems:
- The fan switch on the thermostat is set to "on" instead of "car".
- Relays in the control panel are stuck in the closed position, so the blower is getting a continuous supply of electrical power, and the control panel must be changed.
- The thermostat also has contacts that manage power to the furnace, and they can be worn, so the thermostat should be replaced.
7. Why Does the Heating System Keep Shutting Off?
If your heater burner lights but the heating system quickly shuts down, there are a few common problems that may cause this:.
- The furnace filter is unclean and must be cleaned or replaced.
- The flame sensing unit isn't working and need to be replaced.
- The thermostat is failing.
- While these prevail, there are a number of other prospective causes finest identified by a heater professional. This video gives thorough coverage to the issue of heater short-cycling.
8. The Heater Runs but Can't Keep your home Warm.
- A dirty filter that need to be washed (only if the washable type) or replaced.
- The filter is the wrong type for your furnace and limits airflow, so must be replaced.
- The filter is set up backwards, a concern that can be examined by trying to find the arrows on the filter frame that show appropriate installation direction with the flow of air.
- Air ducts are leaking, often producing obvious whistling noises, and it is time to have them sealed as recommended by Energy Star.
9. The Furnace Makes Loud Noises.
A loud heating system is usually the outcome of:.
- The furnace being a single-stage design that operates on high capability all the time, so it's going to be loud.
- A bad bearing in the draft motor or the blower motor that must be replaced.
- A leakage in the furnace cabinet, sheet metal plenum or ductwork near the heater that must be tightened.
- A dirty filter, which can also trigger whistling.
10. The Heating System Leaks when AC is Running.
Water condenses on the evaporator coil in your furnace, and if it leakages onto the flooring, the problem is most likely a clogged drain pan or drain line.
11. The Air Coming from the Heating System Smells Bad.
Foul odors from the heater are generally caused by:.
- A really dirty filter that ought to be washed, if washable, or replaced.
- A dead rodent or bird someplace in the system, generally a job for a professional furnace technician.
12. The CO Monitor Going Off.
A carbon monoxide gas alarm should be taken seriously. Turn the heater off at the thermostat. Don't enter into the room where the heater lies. Open doors and windows, and go outside. Call 911 from a mobile phone outside your house.
