Furnace Won't Turn On: Here's What to Do!
Furnace won’t turn on? As a Minneapolis homeowner, a broken furnace during winter may seem like the end of the world. Don’t try to survive all season without a furnace. Contact a heating and cooling company in St. Paul for furnace repair. In the meantime, here’s what to do if your furnace won’t turn on.
Your Furnace is Not Receiving Power
This is a common problem with most furnaces. The good thing is that it is easy to identify and fix. The electric input in your furnace could be damaged or tampered with causing this problem.
To determine whether the furnace is not receiving power, you can check other appliances in your house. If they can turn on, then your furnace is likely not receiving power.
Check the circuit breaker and make sure that it is not switched off. Your furnace will have its own circuit breaker. Check whether it is on or off. If it is off, push it to the on position- but only once. The circuit breaker is supposed to switch off in the event there is a fault along with the power systems. If it switches off after you turn it on, call for furnace repair services in St. Paul, MN.
The Float Switch is Up
A float switch is a sensor that monitors the level of condensate within your furnace. Remember, your furnace burns fuel to warm you up. This burning produces condensate which cools and collects as water within the furnace in a place called the condensate pan.
As it accumulates, it lifts the float switch. This collected water is then drained by a condensation pump because it is usually acidic.
Therefore, if the float switch is up, it could mean that the condensation pump is not working correctly. Check if the drain is clear. If it is not, clear is so that the collected water can drain and the float switch can drop.
Clogged Air Filter
Your air filter prevents dust and debris from being blown into your house. With time, the air filter will accumulate excess dust and clog. Once clogged the furnace will turn off to prevent overheating.
The air filter should be changed frequently to prevent these issues and to keep your furnace running.
Your Thermostat is Acting Up
Your thermostat is important to your furnace. It allows the furnace to turn on automatically once a certain threshold is met. Usually, you will have set this threshold.
Sometimes, thermostats misbehave and lose their programming, explains our friends at Gilmore Heating, Air, & Plumbing, a heating company in Folsom. This makes the reset to their default settings. If this is the case, a simple reset will have your house warmed up again in no time. If you are not sure whether this is the issue, set the thermostat temperatures at 10 degrees hotter than the ambient temperature and observe.
The Blower Motor is Not Working
The blower motor blows hot air through the vents when your furnace is on. You can easily tell whether your blower motor is working by looking at your furnace. Usually, there is a small window on the side of your furnace.
If you look through it, you should see a blinking green light. This is the blower motor. Check whether the light is blinking, if not, call for a furnace repair service company.
