If your electric furnace still isn’t powering up after completing these steps, it’s time to give atrusted HVAC teama call. First, consider how long it’s been since you last changed your furnace air filter. Try replacing your furnace filter and see if that does the trick. In high-efficiency condensing furnaces, if the thermostat is blank it’s usually the pump as it’s tied into the thermostat.
For example, maybe your electric furnace has ten heating elements, but only the first two come on. A common reason here is a dying sequencer that can no longer generate signals appropriately to keep the furnace running normally. Maybe it generates a signal for the first few heating elements then loses track. As we mentioned initially, the clearest sign that you may have a bad heat sequencer is a tripped circuit breaker. You’re almost sure that the sequencer is faulty if the breaker trips right when you start the furnace.
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.
At the very least, a noisy furnace might hint that something is loose within the unit. In case of an overcharge, the fuse will sacrifice itself and blow up instead of your unit. The interiors of mobile homes can vary greatly in material.
Completing your mobile home furnace repair
If you have an older gas furnace that does have a pilot light check to see if the pilot light is out. If it is then refer to your owner’s manual on how to relight it, making sure that you don’t smell any gas in the area. Winter is coming, and with it comes cold temperatures. This means your furnace will be working overtime to make sure you stay warm. But like any machine, there are always going to be problems that pop up along the way.
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
As they reach the end of their life, various parts start to fail so the motor has to work harder to turn the fan. This creates more heat which eventually causes the motors thermal overload protector to shut it off. It may take a month or two for it to fail completely. If that is long enough to get you out of the heating season perhaps you can postpone the expense of a new motor until the next fall. The risk you take is that the motor will fail completely some cold night and you will be looking at an emergency service call.
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.
We recommend this guide to walk you through your repair. The author will walk you through common problems and the steps you need to take to take care of it safely. This may seem like an obvious step, but many people either neglect its importance or forget to do it.
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.
This malfunction is noticeable as your unit will have quick and consistent bursts of activity. These include overheating, blocked air filters, incorrect sizing, or wrong temperature readings. A few reasons your furnace is producing cold air are a clogged filter, incorrect temperature setting, fuel or power shortage, and unlit pilot light. The furnace might also be the wrong size and, therefore, cannot heat the zone it is supposed to.
Fortunately, you can fix the problem with simple repairs. Pilot stays lit, fire comes on, but the fan doesn’t come on. This is an $8 part located on the lower side of the furnace by the fire box. There is no way to test it, you just have to replace it and see if that fixes the problem. You have no idea just how many problems you can avoid with a steady maintenance program. Check out our article about HVAC low air flow issues.
When this happens, it can disrupt your home’s safety and comfort. It is not recommended to address every issue your furnace has with a do-it-yourself solution. But it doesn’t hurt to know a few furnace troubleshooting methods you can try doing. Depending on the issue, you may be able to complete the repair yourself.
Instead, older furnaces will keep running until the temperature gets below a set point. Lastly, older parts can be more expensive to replace. With these things in mind, it may save you more time and money in the long-run to simply replace your furnace now.
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.
