Without a working overload protector, the motor windings heat to the point where the enamel insulation melts, creating an internal short that destroys the compressor permanently. The protector is a 2-dollar part that saves a 200-dollar compressor. If your refrigerator is clicking on and off rapidly (short-cycling), the protector may be repeatedly tripping — investigate the root cause rather than just replacing the protector.\u003c\/p\u003e\n\u003ch3 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:18px; line-height:26px; margin:24px 0 8px 0;\"\u003e2.

R600a is a hydrocarbon refrigerant used in modern domestic refrigerators as a replacement for R134a. It is highly flammable, which means any electrical component near the compressor — including the overload protector — must be sealed or designed to prevent sparking that could ignite a refrigerant leak. Do not substitute a protector rated for R134a compressors onto an R600a system, even if it physically fits. The spark-suppression design differs.\u003c\/p\u003e\n\u003ch3 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:18px; line-height:26px; margin:24px 0 8px 0;\"\u003e3.

Measure resistance across the protector terminals — it should read near zero ohms (closed). If it reads open (infinite resistance) at room temperature, the protector has failed permanently. If the protector reads closed but still trips immediately when the compressor tries to start, the compressor itself likely has a locked rotor or shorted winding. Check compressor winding resistances (Start-to-Common, Run-to-Common) with a multimeter before condemning the protector.\u003c\/p\u003e\n\u003ch2 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:22px; line-height:30px; margin:32px 0 16px 0;\"\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse; border:1px solid #eeeeee; font-family:Arial, Helvetica, sans-serif; font-size:14px;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:40%; background-color:#f4fcfc; padding:12px 16px; border:1px solid #eeeeee; color:#111111; font-weight:bold;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"background-color:#f4fcfc; padding:12px 16px; border:1px solid #eeeeee; color:#333333;\"\u003eDRB12T61A1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:40%; background-color:#fafafa; padding:12px 16px; border:1px solid #eeeeee; color:#111111; font-weight:bold;\"\u003eRefrigerant\u003c\/td\u003e\n\u003ctd style=\"background-color:#fafafa; padding:12px 16px; border:1px solid #eeeeee; color:#333333;\"\u003eR600a (isobutane) compatible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:40%; background-color:#f4fcfc; padding:12px 16px; border:1px solid #eeeeee; color:#111111; font-weight:bold;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"background-color:#f4fcfc; padding:12px 16px; border:1px solid #eeeeee; color:#333333;\"\u003eFlat-type external bimetallic overload protector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:40%; background-color:#fafafa; padding:12px 16px; border:1px solid #eeeeee; color:#111111; font-weight:bold;\"\u003eReset\u003c\/td\u003e\n\u003ctd style=\"background-color:#fafafa; padding:12px 16px; border:1px solid #eeeeee; color:#333333;\"\u003eAutomatic (self-resetting upon cooling)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:40%; background-color:#f4fcfc; padding:12px 16px; border:1px solid #eeeeee; color:#111111; font-weight:bold;\"\u003eQuantity\u003c\/td\u003e\n\u003ctd style=\"background-color:#f4fcfc; padding:12px 16px; border:1px solid #eeeeee; color:#333333;\"\u003e2 pieces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:40%; background-color:#fafafa; padding:12px 16px; border:1px solid #eeeeee; color:#111111; font-weight:bold;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"background-color:#fafafa; padding:12px 16px; border:1px solid #eeeeee; color:#333333;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:22px; line-height:30px; margin:32px 0 16px 0;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:17px; line-height:26px; margin:24px 0 8px 0;\"\u003eHow do I know if my overload protector is bad or if the compressor itself has failed?\u003c\/h3\u003e\n\u003cp style=\"font-family:Arial, Helvetica, sans-serif; color:#333333; font-size:15px; line-height:24px; margin:0 0 16px 0;\"\u003eUnplug the refrigerator for at least an hour to let everything cool. Remove the protector from the compressor pins (it clips on). Measure resistance across the two protector terminals — at room temperature it should be near 0 ohms. If it is open (infinite), the protector is bad. If it reads closed, measure the compressor windings directly at the three pins on the compressor: Start-to-Common, Run-to-Common, and Start-to-Run. The two smaller readings should add up to approximately the largest reading. If any winding is open or shorted, the compressor has failed and a new protector will not fix the problem.\u003c\/p\u003e\n\u003ch3 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:17px; line-height:26px; margin:24px 0 8px 0;\"\u003eCan I use this protector with R134a or R290 compressors?\u003c\/h3\u003e\n\u003cp style=\"font-family:Arial, Helvetica, sans-serif; color:#333333; font-size:15px; line-height:24px; margin:0 0 16px 0;\"\u003eThis protector is designed for R600a systems. While it may physically fit compressors using other refrigerants, the trip current and temperature curve are matched to the characteristics of R600a compressor motors. Using it on an R134a compressor could result in nuisance tripping (protector opens too early) or failure to protect (protector does not open when it should). For R290 (propane) systems, similar hydrocarbon-compatible protectors are required but the electrical ratings may differ. Match the protector to the compressor's specified replacement part number whenever possible. \u003ca href=\"https:\/\/koeed.com\/pages\/request-for-quote\" style=\"color:#0056B3; text-decoration:underline;\"\u003eContact us\u003c\/a\u003e with your compressor model if you need help identifying the correct protector.\u003c\/p\u003e\n\u003ch3 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:17px; line-height:26px; margin:24px 0 8px 0;\"\u003eDoes this protector come with a PTC start relay, or do I need that separately?\u003c\/h3\u003e\n\u003cp style=\"font-family:Arial, Helvetica, sans-serif; color:#333333; font-size:15px; line-height:24px; margin:0 0 16px 0;\"\u003eThis listing is for the overload protector only — the PTC start relay is a separate component that plugs onto different compressor pins. The two often fail at different times. If your refrigerator hums for a few seconds and then clicks off (the protector tripping), suspect a failed start relay that is not disconnecting the start winding. If the refrigerator is completely dead and the compressor is cold but the protector reads open, the protector itself has failed. Many technicians replace both the relay and protector together as a pair since both age thermally, but you can replace just the protector if the relay tests good.\u003c\/p\u003e\n\u003ch3 style=\"font-family:Arial, Helvetica, sans-serif; color:#111111; font-size:17px; line-height:26px; margin:24px 0 8px 0;\"\u003eThe new protector trips immediately — did I get the wrong one?\u003c\/h3\u003e\n\u003cp style=\"font-family:Arial, Helvetica, sans-serif; color:#333333; font-size:15px; line-height:24px; margin:0 0 16px 0;\"\u003eIf a new, correctly-spec protector trips immediately, the problem is almost certainly the compressor, not the protector. The most common cause is a locked rotor (compressor mechanically seized) or shorted start winding. The compressor will hum loudly for 1-5 seconds before the protector opens. Measure the compressor winding resistances and check the amp draw at start-up using a clamp meter. Normal locked-rotor amps for a domestic refrigerator compressor can exceed 10A momentarily — the protector should hold for a few seconds before tripping. Instant tripping usually indicates a dead short.\u003c\/p\u003e\n\u003cdiv style=\"background-color:#16c8c8; padding:24px 32px; margin:32px 0; text-align:center; font-family:Arial, Helvetica, sans-serif; border-radius:4px;\"\u003e\n\u003ch3 style=\"margin:0 0 12px 0; color:#ffffff; font-size:20px; line-height:28px;\"\u003eServicing multiple refrigeration units?\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 16px 0; color:#ffffff; font-size:15px; line-height:22px;\"\u003eSend your parts list to \u003cstrong\u003eMoritta@KOEED.COM\u003c\/strong\u003e for consolidated pricing on relays, protectors, thermostats, and compressor accessories.\u003c\/p\u003e\n\u003ca href=\"mailto:Moritta@KOEED.COM?subject=RFQ%20Compressor%20Protectors%20Bulk\" style=\"display:inline-block; background-color:#ffffff; color:#0056B3; padding:12px 24px; text-decoration:none; font-weight:bold; border-radius:4px; font-size:15px;\"\u003eRequest a Quote →\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border:1px solid #0056B3; padding:16px 24px; margin:16px 0; text-align:left; font-family:Arial, Helvetica, sans-serif; border-radius:4px;\"\u003e\n\u003cp style=\"margin:0 0 8px 0; color:#111111; font-size:15px; line-height:22px;\"\u003eNeed start relays, run capacitors, or thermostats as well?\u003c\/p\u003e\n\u003ca href=\"https:\/\/koeed.com\/collections\" style=\"display:inline-block; color:#0056B3; padding:6px 18px; text-decoration:none; font-weight:bold; border:1px solid #0056B3; border-radius:4px; font-size:14px;\"\u003eBrowse All Components →\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border:1px solid #eeeeee; background-color:#f4fcfc; padding:16px 24px; margin:16px 0; font-family:Arial, Helvetica, sans-serif; border-radius:4px;\"\u003e\n\u003cp style=\"margin:0 0 4px 0; color:#111111; font-size:15px; font-weight:bold;\"\u003e\u0026gt; Looking up Modbus communication or CRC errors on your automation network?\u003c\/p\u003e\n\u003cp style=\"margin:0 0 8px 0; color:#333333; font-size:14px;\"\u003eUse the KOEED Modbus CRC Calculator for frame generation and validation.\u003c\/p\u003e\n\u003ca href=\"https:\/\/koeed.com\/pages\/modbus-crc-calculator\" style=\"color:#0056B3; text-decoration:underline; font-weight:bold; font-size:14px;\"\u003eOpen Modbus CRC Calculator\u003c\/a\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-family:Arial, Helvetica, sans-serif; color:#555555; font-size:13px; line-height:20px; margin:24px 0 8px 0;\"\u003e\u003cem\u003ekoeed.com — Your Trusted PLC Supplier.
