85E
Samsung 85E on a refrigerator: compressor under voltage
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On a Samsung refrigerator, 85E flags compressor under voltage and 86E over voltage. Samsung says to unplug it or switch off its breaker for 60 seconds and restore power; if the code returns, contact its support centre.
Safety first
Stop and check this first
- If the code coincides with storms, do not keep resetting while it lasts: each surge hits the appliance again. Wait until it passes and do the 60 second reset once.
Safe checks you can perform
- Exact code: 85E, 86E or 85C
- 60 second reset
- Outlet voltage measurement

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Refrigerator supply measurement
What they doThe electrician measures the voltage at the outlet and checks whether it drops when other appliances in the home start.
They must show youthe values measured at the outlet.
In writingthe measurements and any correction made.
Board and compressor diagnosis
What they doIf the installation is fine, Samsung service checks the compressor board and error history with its diagnostic equipment.
They must show youthe error history reading and the board measurements.
In writingthe diagnosis, any part replaced and the reason.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Exact code: 85E, 86E or 85C
- Who:
- you, no tools.
- How:
- check which code appears and whether it coincided with a storm, a power cut or another heavy appliance starting.
- Result that matters:
- whether it is under voltage, over voltage or the harmless 85C notice.
- If 85C:
- Samsung says to press OK for 3 seconds to clear it.
- If 85E or 86E:
- go on to the 60 second reset.
- Evidence to keep:
- photo of the display and a note of what was happening at home.

60 second reset
- Who:
- you, at the plug or breaker.
- How:
- unplug the refrigerator or switch off its breaker for 60 seconds and restore power, as Samsung says for this group of codes.
- Result that matters:
- whether the code clears and the refrigerator cools again.
- If it clears:
- it was a one-off supply event.
- If it returns:
- Samsung says to contact its support centre; measuring the installation is also worthwhile.
- Evidence to keep:
- time of the reset and whether the code returned.

Outlet voltage measurement
- Who:
- an electrician.
- How:
- if the code repeats, an electrician measures the voltage at the refrigerator outlet, including when the home is using more power.
- Result that matters:
- whether the installation voltage is stable and correct.
- If it is not:
- the fix is in the installation.
- If it is correct:
- the fault is in the appliance; Samsung service.
- Evidence to keep:
- measured values in writing.
Mains voltage is measured by an electrician with a suitable instrument; do not open the outlet or the consumer unit.

What it means
Samsung US places 85E and 86E in the voltage or power error group: 85E is compressor under voltage, possibly a brown out, and 86E is over voltage, possibly a surge such as during a thunderstorm. The board protects the compressor by stopping it if the voltage is not suitable. 85C is a different notice: low voltage detected, which Samsung calls harmless and clears by pressing OK for 3 seconds. If 85E returns after the reset, there may be a persistent problem in the home supply or the appliance electronics; the code does not tell them apart.
Warnings and stop conditions
- Mediumeditorial warning
If the code coincides with storms, do not keep resetting while it lasts: each surge hits the appliance again. Wait until it passes and do the 60 second reset once.

Symptoms and causes
Probable causes · in order
- One-off dip or surgeCommon
The cause Samsung suggests for 85E (brown out) and 86E (surge, for example in a thunderstorm). Fits if the code clears after the 60 second reset.
Evidence: Samsung USA refrigerator error codes
- Installation voltage out of rangePossible
Suspected if the code returns often, especially at times of heavy use in the home. Only an electrician's measurement confirms it.
Evidence: Samsung USA refrigerator error codes
- Refrigerator electronicsPossible
If the installation is fine and the code returns, Samsung says to contact support. The technician checks the board and compressor.
