My problem is my heater turns on, but the fan does not blow heat out. Is there some kind of switch like a thermostat to get the fan going? However, you might find yourself in a situation where your electric furnace continually trips your circuit breaker.
This usually happens when only the first heating element comes on, but the others don’t. The heat sequencer is a mall circuit designed to help stabilize circuits and quickly turn switches ON and OFF. Generally, the sequencer stages different parts of the heating system to prevent overloading or tripping of the circuit breaker. Other appliances that use sequencers include engines and mechanical devices, where the sequencer prevents overheating and overloading. Have you ever come home, switched on your electric heater, and instead of the unit starting to heat up, it instead trips the circuit breaker and goes off? Every year we field 1000's of tech calls for electric furnace not working properly or my fan quit working and my heater blows only cool or luke warm air.
Furnace Problems: 10 Common Issues & Easy Solutions
If the heat produced remains the same, then there must be a problem somewhere. Do this, especially if you’ve recently experienced a power surge or outage. It’s true that sometimes the problem might be huge and can’t be solved without the help of a professional. Needs to review the security of your connection before proceeding.
As a result, only the necessary parts of the heater are on at any given time, meaning that the furnace users only a fraction of the power at its disposal. This helps keep circuits from blowing, motors from overheating, and the various components wearing too fast. Remember that the heating elements in an electrical furnace are coils that warm up when electrical current passes through them. For instance, if your electric furnace has six conduits or heating elements, all six will attempt to draw power from the supply when you switch on the heater. Unfortunately, your home’s supply cannot supply six heating elements at a go.
Completing your mobile home furnace repair
You also can simply buy new ones to replace the old ones. Many gas furnace problems come from your filter or pilot light. Most newer furnaces have an automatic ignition that makes it easy to relight a pilot flame or does away with the pilot light altogether. So, with the furnace off (make sure to double-check this), all you need to do is remove one pair of wires and connect the wires directly. If heating resumes once you bypass the heat sequencer, then the sequencer might be dead or dying.
Check the batteries and replace them if they are no longer functional. Electric furnaces can also trip breakers and blow fuses from time to time, so be sure to check your furnace’s breaker and reset it if it’s been tripped. If you have an old-fashioned fuse box, check to make sure the fuse for your furnace isn’t burnt out. The furnace may have an insufficient power supply which means the furnace is not receiving enough voltage from the circuit breaker. To resolve these issues, try resetting the furnace by turning off the circuit breaker for 20 minutes then turning it back on again. Furnace short cycling is when your furnace turns on and off repeatedly in short intervals.
After your mobile home furnace repair
Additionally, dirt accumulation is removed from the blower motor. Finally, checking the air intake on the mobile home furnace ensures that the air moves freely. The good news is that bypassing the heat sequencer is also a straightforward process.
Take out your multimeter and connect the leads to the heat sequencer. You need to connect the probes to the locations where you just removed the wires. If you’ve observed one of the signs above, you can test your heat sequencer to confirm whether it’s indeed damaged. Fortunately, it’s not too difficult to test a heat sequencer.
How Does the Furnace Sequencer Work?
Many people are usually stranded and have no idea how to deal with the situation. Before they know it, they start panicking because their electric furnace won’t turn on. Any kind of strange noises coming from your furnace that can’t be easily identified or fixed with a reset could be the sign of something more problematic.
Resetting a furnace is an underappreciated skill among many homeowners, and it’s one that’s critical whether you have a gas or electric furnace. In many electric furnaces, a red or yellow reset button is usually inside the blower housing next to the blower motor located near the top of the furnace. If you’re wondering, yes, you can bypass the furnace’s heat sequencer. This is never a good idea, considering the importance of the sequencer. The opposite is also possible, i.e., the heating elements may turn on but not the blower.
Read on to understand more about the sequencer, how it works, what it does, and what can go wrong with your heat sequencer. We also discuss how to test, fix, and bypass the sequencer. Assuming you have fuel, this would indicate a problem with the gas valve.
When you are troubleshooting a heating system, one of the usual problems you will encounter is a dirty filter. This is because the dust and other particles accumulate in the filter. As time passes, your filter will become blocked with dirt and won’t work as efficiently.
We will carefully take you through these procedures and hopefully, revive your electric furnace. Although you expect a certain level of noise from your furnace, there are a few sounds that should not be ignored. Booming, clanging, clicking, and screeching sounds can be signs of trouble.
Beyond basic maintenance, it’s not a bad idea to get furnace inspections either bi-annually or annually. Inspections ensure early detection of significant potential problems. The technician will conduct specific testing of the equipment using a standardized procedure. This inspection will help you take steps to alleviate the problem before it worsens and causes a major repair or replacement. A clogged furnace filter can indirectly cause your furnace to short cycle making it harder for your furnace to keep your home warm.
Verify the blower motor's belt is not frayed, worn or broken. When the belt is too loose it causes the blower motor to malfunction. Dirty electrical furnaces don't work well or efficiently. Electric furnaces pull air through a filter before it heats it. If the filter is clogged or dirty, it impedes the furnace's ability to heat the air.
It could be a straightforward solution or your furnace telling you that it is time for maintenance. For a gas furnace, your pilot light may be out or there is something wrong with your gas line. The furnace is located in the top compartment, connected to several pairs of wires. Each of these wire pairs attaches to a different heating element/conduit inside the furnace. There are many benefits to using furnace sequencers on your electric furnace.
