Description
Product Description
Restore reliable compressor starting and protection with the genuine OEM relay/overload combination part number TJ90RO41, designed for many refrigerators. This unit helps engage the compressor’s start winding and protects it from overheating or locked-rotor conditions. ([AppliancePartsLowes listing confirms: “Relay Overload Comb. Part # TJ90RO41”.)

Because compressor relay/overload combos vary in mounting style, amperage spec, and connector configuration depending on model and production year, please check with your maintenance technician prior to ordering to ensure this is the correct replacement for your specific appliance model.
Features & Benefits
-
OEM-engineered for correct fit and function: Designed to replace earlier numbers such as 21310, AP92, IC13, RO41. Yesparts+1
-
Protects compressor: The overload portion prevents the compressor from drawing too much current or overheating; the relay engages the start winding to allow proper compressor start-up.
-
Restores starting reliability: If a compressor struggles to start or hums/buzzes but does not run, replacing this relay/overload combo often resolves the issue.
-
Cost-effective repair: Rather than replacing the entire compressor assembly, this part can restore functionality for a fraction of the cost when the fault is in the start circuit.
Common Symptoms That Indicate Replacement Is Needed
-
The refrigerator compressor hums but doesn’t kick into full operation (i.e., the unit doesn’t cool).
-
You hear clicking or repeated attempts to start the compressor with no success.
-
The fridge runs excessively long, but doesn’t reach proper temperature — suggesting the compressor may be working harder due to improper start.
-
The previous overload visibly burned, melted, or the relay has worn / damaged terminals.
-
The part number on the old relay shows one of the predecessor numbers (21310, AP92, etc.) indicating this replacement may fit. Yesparts
Cross Reference / Alternate Part Numbers
-
Replaces / is compatible with: 21310, AP92, IC13, RO41. Yesparts+1
-
Also referenced as TJ90RO41 in many catalogs for compressor start-assist applications.
Compatibility Notes
-
Confirm your appliance’s exact model number and check the existing relay/overload’s part number or physical shape and connector tabs.
-
This part addresses the compressor’s start system only — if the compressor is seized, shorted, or the sealed system has a refrigerant issue, replacing the relay/overload alone may not restore full cooling.
-
Installation requires disconnecting power, accessing the compressor start circuit (typically at the rear of the refrigerator), replacing the unit and ensuring all wiring is secured and terminals are tight.
-
After installation, monitor the compressor’s operation: it should start smoothly, the overload should not overheat, and the temperature should begin dropping into normal range.
