Frigidaire Refrigerator HI Error Code: What It Means and How to Fix It

A blinking HI (or H) on a Frigidaire refrigerator is the high-temperature alarm. The fridge or freezer has been too warm for more than an hour, usually because a door was left open. It's often something you can fix yourself in minutes, but check your food first.

Searching for "H1"? On a seven-segment display, "HI" can easily look like "H1." Frigidaire's support pages list H and HI as the high-temperature alarm and don't list an H1 code, so if your fridge is beeping and showing what looks like H1, treat it as HI.

What the HI code means

Frigidaire calls this a High Temp error code. Frigidaire says HI blinking on the display "indicates the temperature is too high in the refrigerator or freezer for over one hour." When it's active, a "High temp" light comes on next to the Clear Alerts button, and an alarm sounds every 60 seconds until you acknowledge it.

HI is a warning, not a part failure. It tells you the fridge got warm. Your job is to work out why, and whether your food is still safe.

Look-alike code: PF (or a Power Failure light) means the power went out or there was a power surge. Frigidaire notes a power outage can also set off the HI alarm, so you may see both after a storm.

Likely causes (most common first)

1. A door left open too long. This is the most common trigger, according to Frigidaire.
2. Something blocking a door, so it looks closed but isn't sealing.
3. A dirty or weak door gasket. Frigidaire says a non-sealing door causes unstable temperatures.
4. Temperature settings changed, sometimes by accident while cleaning.
5. Blocked air vents inside the fridge or freezer.
6. A recent power outage. Frigidaire links PF outages to HI alarms.
7. Poor location. Frigidaire doesn't recommend installing the fridge where the temperature drops below 55°F, such as an unheated garage.
8. A real cooling problem. If HI keeps coming back with the doors shut and seals good, something inside isn't cooling properly.

How to fix it, step by step

Work through these in order. Give the fridge time to recover after each change.

1. Check your food first. FoodSafety.gov says to throw out perishable fridge food (meat, poultry, fish, eggs, leftovers, soft cheeses, milk) that has been at 40°F or above for more than 2 hours. Frozen food that still has ice crystals or is at 40°F or below can be refrozen.
2. Acknowledge the alarm. Press Clear Alerts and read the highest temperature shown. That number helps you judge food safety.
3. Close and check every door. Make sure nothing is blocking a door, bin, or drawer.
4. Do the dollar-bill seal test. Close the door on a dollar bill and tug it out. Frigidaire says you should feel some resistance. If it slides out easily or drops, the seal isn't strong enough. Try several spots around each door.
5. Clean the door gaskets. Use warm, soapy water, as Frigidaire recommends, then dry them.
6. Reset the temperatures. Set the fridge to 37°F and the freezer to 0°F. Frigidaire's acceptable range is 33°F to 47°F for the fridge and -6°F to 6°F for the freezer.
7. Clear the vents. Move food so it isn't touching or covering the air vents.
8. Check the power. Make sure the control panel or interior lights are on. If the fridge is on a GFI outlet, make sure it hasn't tripped.
9. Reset the control if the alarm won't clear. Frigidaire says that, depending on your model, you can unplug the fridge for 30 seconds and plug it back in. If you can't reach the plug, flip its breaker off and on, but note this resets everything else on that circuit.
10. Wait 24 hours. Keep the doors shut as much as possible. If HI returns with the doors and seals in good shape, the fridge has a cooling problem. Go to "When to call a pro."

Test the part

For HI, the parts you can safely check are the door seal and the temperature itself. The cooling parts (fans, defrost system, compressor) are behind panels or in the sealed system and are for a technician.

1. Unplug the refrigerator before you clean or closely inspect the gaskets.
2. Inspect each gasket all the way around. Look for tears, gaps, flattened spots, or sections pulled away from the door.
3. Look at the door hinges and door edges. Check that each door sits flat against the cabinet with no obvious sag.
4. Plug the fridge back in and close the doors.
5. Repeat the dollar-bill test at the top, bottom, and both sides of each door. Mark any spot where the bill slides out easily.
6. Check the real temperature. Put an appliance thermometer (the FDA recommends having one) in the middle of the fridge and another in the freezer. Read them after 24 hours, and compare with Frigidaire's acceptable range (33°F to 47°F fridge, -6°F to 6°F freezer).

If the seals pass and the temperature is still out of range after 24 hours, stop there. That points to a fan, defrost, or sealed-system problem, which isn't a DIY job.

Safety notes

When to call a pro

Call Frigidaire to schedule service, or use a qualified appliance technician, if:

• HI keeps coming back after 24 hours with the doors closed, seals passing, and settings correct.
• The fridge or freezer won't get cold at all, or the temperature keeps climbing.
• A gasket is torn or a door won't sit flat. Replacing a gasket or realigning a door is doable for some owners, but a technician can confirm the cause.
• You'd need to remove panels to check fans or the defrost system. That takes tools and some skill, and anything involving refrigerant needs an EPA-certified technician.
• The fridge was installed in the last 30 days. Frigidaire says to go back to your installer first. After 30 days, contact Frigidaire.
