Foodsavers can change your meal prep game, but they are not without issues. If the lights on your handy FoodSaver keep blinking, use them as clues for troubleshooting.

What Does it Mean When All the Lights on My Foodsaver Are Flashing

A FoodSaver unit can be a real lifesaver for anyone who doesn't like to waste food. While the practical appliances certainly play an important role in many kitchens, they can act up from time to time. While the two or three lights on your FoodSaver may seem like they are just flashing for no real reason, this blinking can often help troubleshoot common issues.

When the Red "Seal" Light Flashes

Perhaps one of the most common issues that FoodSaver users come across is a flashing red light labeled "Seal." If your light like this keeps flashing at you, just let the unit cool. Remember that FoodSavers run at high temperatures, so they need about 20 seconds in between each seal before they are ready to go again.

If you're being patient in between seals and this light keeps flashing, you may have another common issue. Sometimes, the latch simply isn't down all the way. Thus, the FoodSaver cannot seal properly. Pick the latch up and try closing it all the way. This should get your unit up and running again.


Keep this warning light from coming on by storing your FoodSaver properly. Store it horizontally with the latch only halfway down in between uses.

"Tray Full" Light Flashing

Kitchens and their many appliances can get messy in a hurry, and your FoodSaver is no exception. If the LED labeled "Tray Full" keeps flashing at you, it is time to clean the drip tray from your unit and give it a good clean. Once it's squeaky clean and dry, you can replace it and your FoodSaver should start working as usual.


Sometimes, the "Tray Full" light remains on, even after you clean the tray. This is because there is some moisture on the tray. You can use a hair dryer to quickly remove the moisture before replacing the tray.

No Lights Come On

Sometimes FoodSavers can give you a scare when no lights turn on at all. If this happens, check to see if the outlet is working. Your kitchen may be running too many appliances at once, which could cause your breaker to trip. For battery-powered units, the problem may simply be that it needs a good charge. When you plug it in, make sure that the indicator light comes on to show that it is charging.

FoodSavers can be finicky, but they can be well-worth the effort. Take some time to get to know your unit's indicator lights and what they mean, and you can have a much better time using this machine.
