Side-by-Side Refrigerator Problems: 6 Common Faults, 5 First Checks and 4 Dispenser Checks
What Are the Common Problems With a Side-by-Side Refrigerator?
Six faults are the ones to check first on a side-by-side refrigerator.
- The ice maker stops making ice
- The water dispenser gives no water or only a weak flow
- Frost builds up in the freezer
- One compartment is too warm
- Water leaks inside or under the refrigerator
- The refrigerator makes an unusual noise or runs constantly
These are symptoms and not faults that belong to one type, and the model number decides the parts and the manual. This page gives no part numbers or figures from memory.
What makes a side-by-side refrigerator different?
On most models a tall freezer and a tall refrigerator compartment sit side by side, and many have a dispenser in the door. The manual for the model shows the layout and the parts.
What Should You Check First on a Side-by-Side Refrigerator?
Check the power, the setting, the seals, the vents and the level before you look for a fault.
Safety notice: Unplug the refrigerator before touching any part behind a panel, and keep water away from the plug and the outlet. Electrical testing, refrigerant handling and sealed-system work belong to a technician.
Five checks come in order:
- Check that the plug is seated, that the outlet has power and that the breaker has not tripped.
- Check that the temperature setting has not changed, as the manual shows.
- Close each door on a strip of paper, and check that the seal grips all the way around.
- Check that no food or ice blocks the vents inside either compartment.
- Check that the cabinet is level and that nothing stops a door from closing.
A refrigerator that stays faulty after these checks needs the specific checks below. Difficulty: easy.
Why check the simple causes first?
A loose plug, a changed setting or a door that does not close can mimic a fault, and these checks cost nothing. A warm load of food or a long power cut can also leave a compartment warm, so give the refrigerator time to recover before you decide that it has a fault.
Why Is My Side-by-Side Ice Maker Not Working?
A lack of water, a warm freezer or a failed part stops the ice, and the checks are in refrigerator ice maker not working. Many side-by-side models make the ice in the freezer compartment and deliver it through the door, so a jam in the chute or clumped ice in the bin belongs to the same system. Photograph the ice and note where the problem shows, because that record helps the diagnosis.
Does a warm freezer stop the ice maker?
Yes. An ice maker cannot make ice in a freezer that is too warm, so check the freezer temperature before the ice maker. Read an appliance thermometer in the freezer, and compare it with the manual.
Why Is My Side-by-Side Water Dispenser Not Working?
No water or a weak flow comes from the supply, the filter or a dispenser part, and four checks narrow it down.
Safety notice: Keep water away from the plug and the outlet, and unplug the refrigerator before touching any part behind a panel. Electrical testing, refrigerant handling and sealed-system work belong to a technician.
Four checks narrow down a dispenser problem:
- Check that the supply valve is open and that the water line is not kinked, where you can see it without moving the refrigerator.
- Check that the water filter is seated as the manual shows, and replace it if it is due.
- Check that the dispenser pad or lever moves freely and that nothing blocks the outlet.
- Check for ice blocking the outlet or the line, and note it.
The causes and the fixes are in refrigerator water dispenser not working. Difficulty: easy for the checks, and technician-assisted when a valve or a line must be replaced.
Does a weak flow always mean a clogged filter?
No. A kinked line, a partly closed valve or ice in the line can also weaken the flow, so check the supply first.
What Causes Frost, Leaks or a Warm Freezer?
Warm, moist air from a door that leaks builds frost, and a blocked drain or a loose water line can leak water. The causes of frost, with the defrost parts, are in refrigerator frost problems. Water on the floor can also come from the dispenser line or the ice maker line, so note where it appears before you search for the cause.
Can a door that does not close cause frost?
Yes. A door that sticks open a crack lets warm, moist air in, and the moisture freezes as frost. Check the seal and the level first.
Why Is One Side Warm While the Other Side Is Cold?
A blocked vent, a stopped fan or a stuck damper can leave one compartment warm while the other stays cold. Clear the vents first, and check that nothing blocks the airflow between the compartments. A fan that does not turn, a damper that does not move and any sealed-system fault need a technician.
Can overfilling cause a warm compartment?
Yes. Too much food blocks the vents and the airflow, so clear the vents and let the load settle before you judge the cooling.
What Should You Record Before You Call for Help?
Record the model number, the symptoms and what you checked, because that information speeds the diagnosis. Photograph the label, the dispenser, the ice and any frost or water. Note when the fault started and whether it follows a power cut, a move or a change of setting. Keep the purchase record, because warranty terms differ. Ask the warranty provider to confirm the cover in writing, and read the terms for the part and the labor before you book.
When Should You Call a Technician?
Call a technician when the checks find nothing, a compartment will not cool or you see damage or burn marks. A fan that does not turn, a compressor that is loud, hot or clicking, an oily residue, water near the wiring and any sealed-system fault need a technician. Stop and unplug the refrigerator if you smell burning. Give the technician the model number, the symptoms and what you checked. Under warranty, call the manufacturer first, because the warranty terms decide who may repair it. Otherwise, ask for a written quote that names the fault.
