Refrigerator PTC Start Relay, 2-Pin

A two-pin PTC start relay gives a refrigerator compressor a starting assist, and this replacement is intended for common issues such as a compressor that will not start. It is listed for several mini-fridge and beverage-cooler models, but the fit depends on matching the part itself—not just recognizing the refrigerator brand.

Picture a mini fridge that clicks repeatedly while the compressor stays off: a faulty start relay could be one cause, though those symptoms do not confirm it on their own. Compare the old relay before ordering or replacing it.

Getting the most from it

Start by checking the removed relay’s shape and pin arrangement against the replacement. The listed dimensions are about 1.77 x 1.25 x 1.06 inches. Compare those measurements and the physical layout with your existing part, without that measurement, a model-name match alone leaves room for a mismatch. Disconnect power before inspecting or working on refrigerator components, and seek qualified help if you are unsure how to make the repair safely.

The listing names models including ZHB35-120P15, ZHB54-120P15, ZHB45-105P15, ZHB69-120P15, ZHB75-120P15, ZHB60-120P4.7, and ZHB60-120P15. It also lists other ZHB models and says the relay may fit refrigerators and coolers from several brands. Treat those names as a starting point, not a substitute for checking the original relay’s appearance and pins.

Why it’s worth it

If the relay is the source of the starting problem, replacing this component may offer a more focused repair than replacing the whole refrigerator. That makes it relevant for owners trying to get a mini fridge, wine refrigerator, or beverage cooler running again. Worth considering if you have identified the relay as the likely problem and can compare it with the part already installed.

There is a practical trade-off: if you prioritize a replacement matched by its actual shape and two-pin layout, this listing gives you details to compare. If you prefer a part confirmed solely by an exact appliance model lookup, the compatibility information here may not provide enough certainty on its own. A start relay also will not address a compressor fault or another cause of the same symptoms.

Key features

This is a two-pin PTC compressor starter, with a listed size of about 1.77 x 1.25 x 1.06 inches. The description presents it as a replacement for common refrigerator, mini-fridge, wine-cooler, and beverage-cooler repairs. Named compatible examples include models from the ZHB series, along with references to Danby, Haier, Midea, Panasonic, Siemens, Samsung, Vissani, Magic Chef, and others. Confirm the old part’s configuration rather than assuming every model from a listed brand uses the same relay.

One cosmetic caveat is disclosed: an individual relay may have a small scratch. The listing says this does not affect use, but buyers who expect an unmarked part may find that detail worth noting.

Should you buy it?

It may suit a repair where the existing component is a two-pin PTC starter, the dimensions and appearance line up, and the compressor symptoms point toward a possible relay issue. It may not suit you if you cannot verify the fit, need certainty from a refrigerator brand name alone, or have not ruled out other causes of a compressor failing to start. The key decision is whether your old relay matches this part—not whether your appliance simply appears on a broad compatibility list.
