The PTC Refrigerator Starter Relay is a critical component designed to provide the necessary initial power boost to start your refrigerator’s compressor. Utilizing Positive Temperature Coefficient (PTC) technology, this relay acts as a reliable switch that automatically cuts off the starting circuit once the compressor is running, ensuring energy efficiency and motor protection.
Available in multiple pin configurations, these 22 Ohm relays are universal replacements for various household refrigerators, freezers, and beverage coolers.
High Reliability: Manufactured with premium materials to ensure stable performance and a long service life under constant cycling.
Optimal 22 Ohm Resistance: Specifically calibrated at 22 Ohms to match the starting requirements of most standard household refrigerator compressors.
Universal Compatibility: Designed to replace damaged or burnt-out relays in a wide variety of brands and models.
Efficient PTC Technology: Quickly increases resistance as it heats up to safely disconnect the start winding once the motor reaches operational speed.
Compact & Easy Installation: Lightweight, plug-and-play design allows for straightforward replacement without complex tools.
To ensure a perfect match for your existing wiring, this relay is available in the following pin layouts:
1-Pin
2-Pin
3-Pin
4-Pin
Component Type: PTC Starter Relay.
Resistance: 22 Ohm.
Color: Black.
Material: High-grade phenolic plastic and conductive alloy.
Household Refrigerators: Restores cooling function when the compressor fails to start.
Chest Freezers: Ensures reliable operation for long-term food storage.
Mini Fridges & Wine Coolers: Compact enough for smaller cooling units.
Water Dispensers: Used in the cooling systems of high-end water filtration units.
How do I know if my relay is faulty? Common signs include a "clicking" sound coming from the back of the fridge, the compressor failing to turn on despite the fans running, or the fridge not cooling at all. You can also test the relay with a multimeter; if it shows "Open" (infinite resistance) or rattles when shaken, the internal PTC disk is likely shattered.
Does the number of pins matter? Yes. You should select the version (1, 2, 3, or 4 pins) that exactly matches the configuration of your original part to ensure the internal wiring and overload protection (if integrated) function correctly.
Can I use a 22 Ohm relay if my old one was 15 or 33 Ohms? While some relays are cross-compatible, it is always best to match the resistance as closely as possible. Using a significantly different resistance may cause the compressor to struggle during start-up or lead to premature failure of the start winding.
