High temp alarm

bad temp sensor

The high temperature alarm or the red light indicator came on because the internal temp is high. This means that the temperature inside your appliance is still too warm. Keep your freezer/frig door closed and the light will go out in a few hours and you'll then be able to adjust temp or keep it as it was before defrosting.

It is a warning that the fridge thinks the defrost heater is bad

Frigidaire side by side Model Ffhs2622msu Flashing H on the... H means that the refrigerator thinks the heater is bad. You'll need to pull everything out of the freezer and remove the back panel inside the freezer. You'll see the silver evaporator coils with the evaporator fan above it.

What does flashing h mean on Frigidaire refrigerator?

Well if the alarm is going off then there is a problem, get it taken car of asap before you ruin a fridge and freezer full of expensive food.

I would make sure they fan on the bottom that cools the condenser is turning easy way to test is. Put a fan in front of the fridge blowing under it if it starts cooling that is now working right

Cud be a couple of different things. Surely it is under warranty.

Hi Heather and welcome to FixYa. I am Kelly. It took me over an hour but I did find your manual online. I first had to realize this was a UK model. Your manual is here:

You may have to go to his page first:

and enter this product code:

858615915000

Per the users manual there is a vaction mode and it is discussed on page 9 of the manual.

The alarms are listed on page 10 of the manual:

The Vacation mode shuts off the fresh food compartment completely and there is not a temp display. The icon is in the lower RH side of the display window and is sleleced with the menu button. Per the manual you should keep depressing the menu button until the Vacation icon is not longer displayed. (Icon is a beach lounger chair and umbrella)

Thanks for choosing FixYa.

Auto defrost system not working properly
staying in defrost to long,door gasket leak
compressor overheat,controls turned up max
all above can cause your problem
even cloged defrost drain

Self defrost mechanism may have an issue. If it stays on too long you will have excessive temps build up in refrig as well as freezer. There is also a defrost thermostat that is supposed to turn compressor back on when temps get too high - check that out also.

Hi,
With the problems it is presenting, I would say it's very likely.
However it may take a bit of detective work to find which board is defective.
