Keeprite Furnace Repair Guide
What’s Wrong With Your Keeprite Furnace?
Take care to ensure that your Keeprite furnace is completely shut off with no access to power before trying to diagnose and repair the issue.
|Is your furnace...
|The problem might be your...
|How you can fix it:
|Most likely, either the electrical system providing your furnace’s power has shorted or the power switch has blown.
|Try resetting your furnace’s circuit breaker. If it has blown, you will need to replace it.
|The furnace’s igniter might either be cracked or faulty.
|Check the part for cracks, if it is then replace the igniter. If it isn’t cracked, use a multimeter to test for continuity.
|Your thermostat might be adjusting incorrectly, causing the furnace to cycle on and off too often.
|If your thermostat has an adjustable calibration scale, adjust the heat anticipator. If this does not stabilize the unit, you may have to replace the thermostat.
|Not blowing hot air?
|Your blower motor may have completely burnt out. If this doesn’t seem to be the case, then the connecting belt may have simply broken.
|Test to see if power is reaching the motor. If it does, but isn’t running, the motor has likely failed. If the motor runs but air doesn’t move, the connecting belt has probably broken. You’ll have to replace the belt.
|Blowing too much air?
|The control board regulates the amount of voltage that reaches each functioning part. If the relay that controls the blower motor has failed, it will continually send voltage to the motor.
|Replace the control board.
|The contact that controls the blower motor on your thermostat may be stuck closed, causing the blower motor to run continuously.
|Use a multimeter to check for continuity. If it appears the thermostat is the issue, replace it.
|Starting and then stopping shortly after?
|Your furnace’s flame sensor monitors the burner, detecting whether a flame is present. If it is either defective or dirty, it will not be able to detect a flame.
|If dirty, clean the sensor using a fine abrasive pad. If faulty, replace the flame sensor.
As with any furnace, a little maintenance goes a long way in extending the longevity of your unit. Ensuring that it is clean, running properly, and has good filters can keep the more expensive repairs at bay. Keeping your furnace in good working order means that it’ll be running at peak efficiency and maintaining a comfortable home for you.
How to Replace Your Air Filter
- Open the front panel or door to get access to your Keeprite furnace; you may have to slide or unscrew the panel to work with progressive force.
- The filter is typically near the cold air return or the blower chamber. Locate it and ensure that you have easy access to it.
- Be mindful of how you pull out the filter, especially if there is an endcap. Slide in the new one (or cleaned old one).
- Take care to insert the filter correctly, that the arrows are pointing in the right direction to go with the blower and away from cold air.
- Put back the panel to your furnace, either sliding or screwing it back in place.
Keeping a clean filter ensures that your furnace’s airway isn’t clogged and working harder than it needs to, to circulate air throughout your home. A clean filter also improves the air quality in your home, which is especially important for people with allergies or breathing issues — double check registers and vents to make sure that the airways are 100% accessible.
