Range Hood Lights Flashing-An Ultimate Guide

Whether you’re cooking or not, it can be annoying when your range hood lights start flashing. Range hood helps you to avoid cooking generated steam to make your kitchen environmental and suitable for cooking. But sometimes its flashing light can be the reason to make you annoyed.

Ever since I got my new Range Hood, it worked absolutely fine and it seemed that it was providing the right to my money.

But suddenly one day some sort of light started flashing. I did not know what to do but thanks to the internet. I surfed the internet and got the issue fixed.

Everything is mentioned in detail in the article. A flashing light indicates that the fan motor has locked up and needs to be replaced.

But the fan motor isn’t what flashes—it’s the light bulb behind the fan that flashes. You can usually fix this yourself in about 10 minutes with just an old toothbrush and some patience!

Turn Off Light

There are two common reasons for range hood lights to flash: either there’s something wrong with your rangehood circuit or it’s a loose wire somewhere else in your house.

Most of us don’t have a complete wiring diagram of our homes. You should start by unplugging and opening up your hood. Do it to see if anything looks broken, melted, or disconnected.

If you find any visible damage, call an electrician to come to fix it. If everything looks fine, disconnect all wires and clean them with rubbing alcohol—this includes light bulbs!—to make sure nothing is touching each other. Reassemble and plug back in. Hopefully, that will solve it!

Range Hood Lights Flashing

Change Bulb

If your range hood light is flashing, it’s not always an indication that you need to replace a bulb.

In some cases, dust or other debris may have entered your fixture and broken one of its bulbs; in these cases, simply clean off those materials and replace them with fresh bulbs.

However, if you find that after replacing several bulbs you still have trouble, it’s likely that your fixture is failing—in which case it will need to be replaced.

Luckily for you (or maybe not), we can fix most range hoods quickly and affordably. First things first: Contact our team for an inspection today!

Replace Circuit Board

One of the easiest ways to fix a range hood is to replace its circuit board. These parts are often inexpensive and easy to install, so they’re one of our favorite DIY solutions.

The exact design or brand of your hood will determine whether or not it has a circuit board, but if you’re not sure where yours is located, check behind or underneath your rangehood for a small component box with switches and wires.

One switch will have a small diagram indicating what parts are supposed to be connected; just take it out and replace it with a new board.

If your new circuit board doesn’t come with instructions, try watching an installation video online before you start. Or ask for help from someone who knows more about electronics.

Replace Switch Assembly

If your range hood lights are flashing on and off, then it may just be that your switch assembly is broken. If that’s the case, you don’t have to call an electrician.

You can fix it yourself and save a lot of money by just replacing your existing switch with a new one. It’s very simple and doesn’t require any experience at all!


Replace Controller

If you have replaced your lighting unit but still experience flashing lights, it is likely that your controller has failed.

A replacement controller can be found at most hardware stores for under $50 and installing a new one is a fairly simple project that requires only basic tools.

Look to install a new one as soon as possible because if it fails, all of your lights will go out immediately, leaving you in darkness.

The best practice for preventing a similar issue with controllers is to replace them once every 5 years.

Install a Delay Circuit

No matter which bulb in your light fixture is failing, you can usually solve the problem by installing a delay circuit.

This simple device will prevent one of your bulbs from coming on until a few seconds after another bulb has already lit up.

This prevents dim bulbs from appearing as if they’re burning out since most people are expecting them to be bright immediately.

Just remember that when you add in a delay circuit, it’s important to ensure that none of your bulbs are burning out or constantly flickering; if so, you may want to replace those bulbs before attempting a repair like this.

Because of how your range hood fan has been wired in with a second switch, that flashing light is probably not an indication of a problem.

In fact, if it’s still working to ventilate your kitchen, there’s nothing wrong with it at all!

Instead of trying to fix what isn’t broken, consider getting a new range hood.

Whether you replace it or get an electrician to come by and fix up your existing hood, having an appliance that looks good and works well in your kitchen is always important.
