Description
Protect the heart of your refrigerator’s cooling system with this genuine OEM overload protector, part DA34-10003S, designed for many Samsung refrigerators. This component attaches to the compressor and cuts off power when the compressor draws excessive current, helping prevent damage from overheating or locked-rotor conditions. Because start-relay and protector assemblies vary by model and year, please check with your maintenance technician to confirm that DA34-10003S is correct for your appliance’s full model number and that the overload protector is indeed the failing component. samsungpartsusa.com+2appliancepartspros.com+2
Features & Benefits
-
OEM specification: Built to Samsung’s original equipment standards for fit, materials and performance. samsungpartsusa.com+1
-
Compressor protection: This overload protector helps safeguard the compressor by interrupting power when the motor current exceeds safe levels, reducing risk of failure and extending compressor life.
-
Reliable replacement: Ideal fix when your refrigerator’s compressor is overheating, runs continuously, or keeps tripping due to overload.
-
Cost-effective repair: Replacing the protector is significantly less expensive than replacing the compressor or sealed system.
-
Straightforward installation: With compatibility verified, the replacement involves removing the old protector, mounting the new DA34-10003S in place, and testing the compressor cycle.
Common Symptoms That Indicate Replacement
-
The refrigerator or freezer won’t cool, and you hear the compressor try to start but then stop, or you hear repeated clicks/attempts from the compressor.
-
The compressor runs but is very hot, the cabinet is warm, and the condenser coils are hot — indicating it may be being overworked due to failed overload protection.
-
The protector has visible signs of failure: burnt, melted housing, or the mounting bracket is loose/damaged.
-
The appliance compressor draws excessive current (confirmed with multimeter), or a technician finds the protector is stuck closed or open.
If you observe any of these, ask the technician to verify that the overload protector (DA34-10003S) is indeed the failing part and not another issue like start relay, compressor windings, or wiring.
Compatibility Notes
-
Samsung lists part number DA34-10003S as a “Compressor Overload Protector / Relay” for certain refrigerator models. samsungpartsusa.com+1
-
It replaces older or related part numbers such as AP4138858, 1924722, PS4138798 in some catalogs. appliancepartspros.com+1

Important: Because compressor assemblies and mounting brackets differ between model lines, production years and regions, it’s essential to verify your appliance’s full model number (including suffix letters) and confirm the exact part required before ordering.
