상품 특징

• Specifications & Cross-Ref (with compatibility wording): 12V DC coil; up to 16A @ 250VAC load switching; 4 PCB pins + two #250 (6.3 mm) quick-connect tabs; rectangular PCB-mount “DU1PU” footprint. Compatible with DEC DU1PU-12VDC / DU1PU 12V form factor and similar boards that specify this relay. Typical use: switching mains to heater/fan/magnetron in appliance control systems. Match coil voltage, footprint and contact rating before ordering.
• Operation & Install Location (how/where it’s used): Designed to be soldered on the appliance’s main control PCB; the coil connects to the two smaller PCB pins, while line/load run through the top quick-connect tabs. Commonly located near the mains input or high-load section (e.g., magnetron drive in microwave controls). Replace with power disconnected; discharge high-voltage capacitors; observe creepage/clearance; re-solder cleanly and verify orientation by PCB silkscreen.
• Compatibility by Form Factor (non-vehicle use cases): Compatible with control boards labeled “DU1PU 12VDC” or having the matching 4-pin pad layout and tab spacing; applicable to microwave ovens (magnetron power relay), small appliance heaters/fans, HVAC defrost/fan controls, vending/control panels, and general industrial controls. Always verify: 12VDC coil, ≥16A/250VAC contact rating, DU-style 4-pin PCB spacing. Not vehicle-specific.
• Fixes Common Symptoms: Resolves “runs but no heat” in microwaves, intermittent heating, audible clicking with no load transfer, welded/burned contacts, or stuck fan/heater. Restores reliable AC load switching when the original DU1PU relay is heat-stressed or contact-pitted. After installation, function-test the coil and confirm contact closure under 12V drive, then run a controlled load test.
• Complementary Parts for a Complete Repair (traffic capture via related needs): Pair this relay with Compatible with 20A/250V ceramic fuse (line protection), Compatible with standard microwave door-interlock microswitch, Compatible with thermal cutoff/thermostat, and Compatible with HV diode/capacitor leads. These items commonly fail or wear alongside the power relay; replacing them proactively reduces repeat tear-downs and callbacks
• What’s Included & Notes: 1× DU1PU-form-factor 12VDC power relay (quantity per your selection). For “like-for-like” replacements only—brand names are used strictly for compatibility identification; this item is an aftermarket replacement part matching the DU1PU 12VDC form factor and ratings.
