If you’re replacing your Broan range hood, you’ll need to reset the clock on the unit before it can be used again.
I also faced the same problem and was unable to fix the problem in the beginning. But, after trying some fixes, I was finally able to get it working again.
This Broan range hood installation video will walk you through how to do this in just five minutes or less.
If your replacement range hood includes new bulbs, skip this process as the light bulbs are installed at the factory and do not need to be reset until they burn out.
Change the filters
Cleaning or replacing your air filters regularly is one of the easiest ways to maintain indoor air quality. If your kitchen exhaust hood has a blinking red light and is not working, clean or replace filters first.
Filters need to be cleaned once every month or so, depending on use, as well as replaced at least once a year.
It’s a good idea to keep a spare filter on hand in case one needs to be replaced during a cooking frenzy.
For kitchen exhaust systems that do not have an onboard light, check with your local home improvement store for an LED filter replacement kit that includes lights and mounting brackets.
The blower isn’t plugged in
Most appliances have an on/off switch and a reset button, so if you’re having issues with blinking lights or multiple beeps you should start there.
Check to make sure your appliance is plugged in correctly and test it before turning it on. If you still experience issues, try pressing the reset button for 15 seconds before turning your range hood back on.
If none of these steps solve your issue, consider calling a professional to fix it for you!
Before replacing any range hood parts, unplug your range hood. Check to see if your blinking light is coming from a burned-out bulb—this may be all you need to fix.
If so, replace your old bulb with a new one and check to see if it fixes your problem. If not, continue on with our troubleshooting guide.
Many range hoods have a light that blinks to let you know it’s time to replace its filters. If your vents do not have a warning light, check when they were last changed.
Before installing new filters, clean them with soap and water or a commercial cleaning solution according to the manufacturer’s instructions. Dry thoroughly before replacing the unit.
Filters should be replaced every two months for maximum efficiency and must be replaced immediately if damaged or dirty. Do not use soft scrub pads or harsh abrasives; doing so can damage your vent’s heating element and fan motor.
Replace The Capacitor
The main culprit in most blinking range hood lights is a capacitor. That’s not a bad word, though. A capacitor simply stores energy, like a battery.
In most cases, when your range hood light starts to blink it means there’s some kind of short circuit in your appliance or one of its components that is causing it to overheat.
Capacitors are often used as protection devices against these types of malfunctions and will temporarily let out extra stored electricity to protect whatever they’re connected to.
Unfortunately, capacitors only last so long (typically five years) and will eventually need replacing if you notice your light starts to blink more frequently or for longer periods of time—the blinking may also seem faster than normal once that happens.
Replace The Motor
Many range hoods utilize a motorized plenum in order to extend or retract exhaust ducting from various components within. When your hood is not functioning properly, there is a good chance that your motor has failed.
If replacing motors seems like something you could tackle on your own, go for it. Otherwise, consider hiring an expert to handle this repair for you; range hoods can be heavy and awkward to work with.
Either way, you should have no trouble finding service providers at home improvement stores or online forums.
If cost isn’t a concern, then buy one from an original equipment manufacturer (OEM) if possible as they tend to hold up better over time than generic options do.
The blinking power light on a range hood typically indicates that there is an error with either safety (like a short in one of your outlets) or with your current setup.
