Things to check when your Furnace(stove) Stops Working

 Modern high-efficiency furnaces are complex pieces of machinery, and most major repairs are best left to knowledgeable gas stove repair home service technicians. But before calling the furnace company and incurring a considerable trip charge, it is sensible to see out three quite common problems that are often easy to remedy yourself: power supply interruptions, thermostat malfunctions, and problems with the condensate drain system.

Is the Power Interrupted?

Just like the other appliance in your home, a furnace that suddenly stops running could also be experiencing an electric power interruption. Sometimes this is often as simple because the ON-OFF toggle on the furnace being accidentally shut off—this can happen, for instance, if you've got kids who fiddle within the utility room. The furnace's switch looks a bit like a standard light fixture switch, sometimes located on the furnace cabinet itself, sometimes on the wall near the furnace. confirm the switch is within the ON position before calling the furnace repair service.

Another common power interruption occurs if the breaker controlling the furnace has tripped and shut off. Locate your main electric service panel and open the door. Find the breaker that controls the furnace, and check to ascertain if it's tripped to the OFF position.

To reset this breaker, first, turn the thermostat to a rock bottom setting to stop the furnace from beginning at the moment you reset the breaker. Then, flip the furnace's breaker back to the ON position. Set the thermostat to a heat setting, and observe the furnaces' behavior. In many cases, simply resetting the breaker will fix the matter.

However, you ought to consider the explanations why the furnace breaker tripped. Sometimes this will indicate a breaker that's starting to fail and means it'll need replacing sometime soon (a job for an electrician). Or, it's going to indicate that the furnace motor is laboring for a few reason. for instance, a badly clogged furnace filter can cause the motor to strain, which may potentially overload the circuit breaker. Or, a nasty capacitator or another component, or an electrical short inside the furnace's wiring, can cause the breaker to trip. Replacing the filter is a simple solution you'll try, but if the breaker trips repeatedly, it's time to call knowledgeable to look at the furnace OR circuit breaker for more serious problems

Is the Thermostat Functioning?

When a furnace stops working, the matter fairly often lies with the thermostat. Checking the thermostat is fairly easy to try to do, and lots of of the fixes are well within the reach of a DIYer.

Look at the clock time: Start by simply checking the automated clock if you've got a programmable thermostat. If the clock is off or sets incorrectly, then the schedule won't operate correctly. Resetting the clock may return the furnace to normal operation.

Check the thermostat's batteries: Many older thermostats operate off of the low-power current from the wire that attaches to the thermostat, in order that they will haven't any batteries. But newer programmable thermostats usually do have onboard batteries designed to stay the inner clock and program intact within the event of an influence outage. If the batteries go dead, the thermostat may pack up. In many cases, simply replacing the battery will return the thermostat—and your furnace—to perfect operating condition.

Check the wire connections at the thermostat: Your thermostat can also malfunction if any of the low-voltage wire connections have come loose. Carefully detach the thermostat body from the wall and check each connection. counting on the complexity of your system, there are often as many as six low-voltage wire connections linking your thermostat to the furnace, or as few as two wires. confirm each low-voltage wire beginning of the wall is securely attached to its corresponding terminal on the thermostat.

Check the thermostat wire connections at the furnace: it is also possible that the thermostat wire connections may need to be loosened at the opposite end—at the furnace itself. Locate the instrument panel on the furnace and check the low voltage thermostat wire connections to form sure they're all secure.

Consider the transformer: Finally, it's possible that the thermostat is malfunctioning due to a drag with the transformer that steps down 120-volt power to the 24-volt current required for the thermostat. Usually built into the furnace, the transformer is found inside the access panel and can have both 120-volt line voltage wires connected thereto, also as low-voltage thermostat wires. Replacing the transformer is typically a matter for a furnace technician because it involves handling 120-volt line voltage wires, testing the transformer with a multimeter, and disconnecting electrical connections. Don't attempt this unless you're very experienced with electrical wiring.

Is the Condensate Pump Working?

Modern high-efficiency furnaces have a two-stage heat exchange design that makes condensed water that's far away from the furnace by a drain line. This drain line may include a little pump if the furnace installer ran a tube for the condensate water to a utility sink or other plumbing fitting. (If there's a handy floor drain near the furnace, the installer may have installed an easy gravity drain tube from the furnace to the ground drain.)

If your furnace is provided with an electric condensate pump, you'll have heard its faint buzzing—a sound almost like that produced by the pump for an aquarium or decorative drinking fountain. This sound is typically heard after an extended heating cycle—the sound runs for a couple of minutes, then stops.

But if the condensate pump becomes plugged or malfunctions, the condensate water may simply spill onto the ground around the base of the furnace. this will be an alarming symptom, but it's actually not all that serious. it's always easy enough to urge the pump to work again—or even replace it entirely. The condensate pump and pan are about the dimensions of a shoebox, usually located on the side of the furnace. Sometimes, it'll be powered by an auxiliary outlet next to the furnace. If this is often a GFCI outlet (it should be), check to form sure the GFCI hasn't tripped. If it has, merely resetting the outlet may return the pump to operate.

Other times, the condensate pump is hard-wired into the furnace and is powered directly by the furnace. If so, close up the breaker (or breakers) controlling the furnace before examining the pump. Start by checking the tube that runs from the condensate pump to the surface and confirm that it's not pinched or blocked.

Open the lid to the condensate pan (usually removing the condensate pump within the process). Check to ascertain if the drawtube remains at rock bottom. The condensate pump pan could be overly full and leaking on the ground. If so, it means the automated turn on the pump isn't working correctly—manually flip the switch back and forth a couple of times to loosen it. If the condensate pump still doesn't work, it'll get to get replaced entirely. Condensate pumps are relatively inexpensive and straightforward to exchange. If the pump is hard-wired into the furnace, though, you'll get to hire an electrician.
