Although it is not a common experience, it can be normal to have flickering lights on a Broan Range Hood. Power is supplied to the lamp as the vent is on LOW setting mode passes through the diode (an electric component). The diode is forced to half the power to match the dimmer setting.
The flicker can be perceived by focusing your eye on an object close/near the lights, especially a highly reflective object such as the cooktop beneath the lights. This problem cannot be solved by changing either the hood or the bulbs.
Troubleshooting
Sometimes a button or a light on your hood flashes. What does this imply? Is your hood trying to communicate something, or is there an issue somewhere? For you to be certain about it, go through the manual for your extractor hood. Sometimes, the blinking of your hood is an indication that you need to replace your filters. Nevertheless, if the issue does not originate from the filters, you will have to do more research, particularly about the electrical system. For more information, here are some of the things you need to check to troubleshoot what might be causing your hood light to blink.
5 Reasons for your Blinking Hood
1. Reset filters after change/replacement
If you have replaced the filters and your hood still flashes, you might have forgotten to reset the signal. After connecting your extractor hood, press and hold the blinking light for a few seconds to reset it and stop blinking.
If you have replaced both types of filters, perform this reset twice. Depending on your hoods, the reset approach can be different. Consult the instruction manual that comes with your appliance to get the correct reset method for your specific hood.
2. The LEDs blink to send a warning that the filters are reaching saturation point.
All hoods are fitted with filters to purify the air once it is sucked in. The carbon filters should be replaced after 3 to 4 months for recirculating hoods. At the same time, the grease filters should be cleaned after every month or two.
To maximize its operation, your extractor hood sends a warning when the filters need a replacement or cleaning. Depending on your hood type, a button, an indicator light, or a beep, means that your hood filters need to be replaced. The signal for a carbon filter is different from that of a grease filter. To understand the meaning of each signal, refer to the instruction manual of your appliance.
To clean your kitchen hood filters, you must first remove them using a simple clip system. Submerge them in hot water with a cup of baking soda, dish soap, or black soap. Allow them to soak for about 30 minutes. Scrub with a soft brush and then rinse with clean water. Allow them to dry overnight, and then reassemble them back.
Some grease filters can be cleaned directly in the dishwasher, but confirm if this applies to your hood in the user manual.
However, your hood will continue blinking after replacing the filter if you do not reset the signal. Refer to point 1 "Reset filters after change/replacement."
3. Bad connection in the electrical system
A false connection can appear in the electrical system of your hood. This will prevent it from turning off. A false contact at the lamp socket can make the lamp flash since the wires are in contact with each other. You can use a multimeter to measure the voltage at the socket connectors. If you have installed a new lamp and it does not turn on, replace the socket.
4. Failure on the power supply
If the lights on your Broan Hood are blinking, it might be a result of failure in the power supply. First, check if the circuit breaker on your electrical panel is on. Check if the connecting dominoes are tight. Finally, use a multimeter to test the voltage on the electrical supply. This is done by putting the tester's tips on the socket's terminals.
5. Transformer or switch problems
Have you replaced your Broan Hood filters? Tested the electrical system? Is it not the socket or the lamp? Then the switch or the lamp may be faulty. They lower the electrical voltage at the lamps. Harm yourself with your multimeter and test the voltage at the voltage. If the voltage coming out of the transformer after activating the switch is below 230 volts, you need to replace it.
Also, the light switch could be out as it allows you to switch the lights on and off. A bad connection at this point may lead to the lamps blinking occasionally. The switch is always fixed behind the control panel. You can test its condition and the voltage using a multimeter.
Frequently Asked Questions
What can I do if my Broan vent fan is not working?
If your rocker switch does not have continuity, change it. To check if the rotary switch is faulty, use a multimeter to test for switch continuity. If you find that the switch rotary is defective, replace it. We supply over 3 million parts of different brands; therefore, we are likely to have the part you require.
What can I do if my Broan range hood does not turn on?
The fan may pulse on/off temporarily and continue with that process, and it has switched on by itself with no heat provided to the stove, but the hood lights are on. If you dim the hood lights or switch them off, the fan will stop the pulse and remain on with the speed light flashing on and off.
How do you troubleshoot a hood fan for an electric range?
Electric range hood fans can suffer the same problems as gas range hood fans, and both use the same troubleshooting method. All hood fans use shaded pole motors, which is the simplest motor to troubleshoot. The fan motor and controls can be removed by unsnapping the filter and loosening the screws fixing the trim.
How long does it take to mount a new Broan fan?
A noisy or loud fan can make you stop using it. Maintain every corner looking and smelling fresh with a new fan grille. With different styles and colors that match most of the ceiling colors and lighting options, it will only take you 5 minutes or less to install. This is one of the fastest, easiest, and most reliable bathroom upgrade options you should consider.
Should there be a light above the hood of the Broan range?
When you turn your Broan range on, the light above the fan speed goes on. At this time, the fan will pulse on/off temporarily and continue with that process, and it has switched on by itself with no heat provided to the stove, but the hood lights are on.
