Introduction
The bimetal defrost thermostat is a critical safety and control component in the automatic defrost system of no-frost refrigerators. It cuts power to the heating element once the evaporator reaches the preset temperature, preventing overheating while ensuring full ice removal.
DA47-00243K is an OEM-spec replacement part designed exclusively for Samsung residential refrigerators. For wholesale distributors, unified part number matching and consistent manufacturing quality are the two core factors that reduce inventory risk and after-sales claims.
1. Full Cross Reference Part Numbers
Distributors often struggle with mismatched search terms across B2B marketplaces and repair databases. All equivalent part IDs for this component are listed below for catalog entry:
– Main OEM part number: DA47-00243K
– Alternative part codes: 2025696, AP4403832, PS4140510
These numbers cover searches on Amazon Business, eBay Wholesale, and professional appliance repair part portals. Adding all codes to your product listing maximizes search coverage.
2. Mechanical & Structural Specifications
1. Thermal Performance
The bimetal contact must trip within the factory-set temperature range with a tolerance no greater than ±2°C. Off-spec thermostats will lead to two common service issues: incomplete defrost with persistent ice buildup, or overheating that melts internal plastic housing.
2. Wiring & Connector Configuration
– Wire type: High-temperature silicone red and black wire
– Terminal: OEM yellow 2-pin plug, direct plug-and-play without wire modification
– Harness length follows the original factory routing to avoid wire tension or interference with evaporator fan operation.
Non-OEM modified connectors will be rejected by professional repair technicians in North American and European service markets.
3. Common Pitfalls in Wholesale Sourcing
Low-cost generic copies of DA47-00243K create major liability for distributors:
1. Incorrect trip temperature: Counterfeit units maintain power to the heater too long, leading to fire hazards and costly customer liability claims.
2. Substandard wire insulation: Ordinary PVC cable melts under defrost cycle heat and causes short circuits.
3. Loose connector latches, resulting in intermittent power failure after short-term installation.
Conclusion
For appliance spare parts wholesalers, the DA47-00243K thermostat requires strict adherence to OEM temperature parameters and original harness construction. Standardizing cross-reference part numbers in your product database will improve inventory turnover and cut down on return rates from repair contractors.
