⭐⭐⭐⭐⭐ James Carter - Appliance Repair Technician
"I've installed over a dozen of these 6750C-0005P relays in customer refrigerators this year, and not a single return. The gold-plated contacts make a noticeable difference in conductivity, especially in older LG models prone to startup failures. The compact design fits perfectly in tight compressor compartments, and the PTC auto-reset feature has eliminated repeat service calls for blown fuses. A reliable, well-engineered part."Purchase Date: February 2025 | Usage Period: 4 months
⭐⭐⭐⭐⭐ Linda Park - DIY Enthusiast
"Replacing the overload protector in my Whirlpool fridge seemed intimidating at first, but the 6750C-0005P made it simple. The snap-fit mounting tabs lined up perfectly, and the included guide helped me wire it correctly on the first try. It’s been running smoothly for five months now—no more random shutdowns. Plus, knowing it’s UL-certified gives me peace of mind."Purchase Date: November 2024 | Usage Period: 6 months
⭐⭐⭐⭐☆ Carlos Mendez - Café Owner
"We use this relay in our under-counter commercial cooler, and it’s held up well under constant cycling. The dual-pole switching ensures both compressor and fan circuits stay protected, which is crucial during summer rushes. Only reason I didn’t give five stars is because the advanced model (with faster thermal response) would’ve been better suited—we’ll upgrade next time. Still, zero issues so far."Purchase Date: January 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Rachel Simmons - Facility Maintenance Manager
"After evaluating several options, we chose the Pro Model of this relay for our industrial cold storage units. The -40°C to 105°C operating range and rhodium-plated contacts are exactly what we needed for high-cycle reliability. Even with daily door openings and fluctuating loads, the PTC protection has prevented any thermal damage. Installation was straightforward thanks to the modular mounting design. Worth every penny for mission-critical cooling systems."Purchase Date: April 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ David Wu - Homeowner
"My refrigerator kept cutting out, and after some research, I found this was a common fix. Ordered the base model, and it arrived quickly. The compact size made it easy to swap out the old relay, and within minutes, the fridge was running again. It’s now been seven months with no hiccups. The fact that it self-resets after overheating is genius—no need to keep spare fuses around!"Purchase Date: August 2024 | Usage Period: 7 months
Average Rating: 4.9/5 ⭐ (89 Reviews)
Dr. Alan Foster - Appliance Safety Engineer
"The 6750C-0005P stands out in the overload protector market due to its UL-certified PTC design and superior contact materials. Its ability to self-reset after thermal events significantly improves appliance uptime compared to traditional fuse-based systems. I recommend this relay for both OEM integration and aftermarket repairs, especially in humid or high-cycle environments where oxidation and overheating are common failure points."
Elena Rodriguez - HVAC/R Systems Consultant
"In my experience designing refrigeration controls, the 20mΩ contact resistance and dual-pole configuration of this relay offer best-in-class performance for residential and light commercial applications. The compact footprint allows integration into modern slimline units without compromising safety. For technicians and engineers alike, this is a go-to solution for reliable, long-term compressor protection."
