First Impressions of Coleman-Mach 70-8890 Wall-Mount Analog Thermostat Heat/Cool
The Coleman-Mach 70-8890 Wall-Mount Analog Thermostat Heat/Cool is a replacement part, pure and simple. It’s not going to win any design awards, but it promises to keep your RV’s temperature regulated like a trusty old hound dog. If your current RV thermostat is on the fritz, causing temperature swings that rival the stock market, this could be your lifeline.
My journey to this thermostat began with a sweltering summer camping trip last year. The factory thermostat in my travel trailer decided to give up the ghost, resulting in a cabin that felt like a poorly ventilated sauna during the day and an icebox at night. I needed a reliable, no-frills replacement that wouldn’t require a PhD in electrical engineering to install.
The Coleman-Mach thermostat arrived in a plain cardboard box, which is pretty standard for replacement parts. My first impression was that it looked… functional. The white plastic casing felt sturdy enough, and the analog dials had a satisfying click when turned.
I considered a digital thermostat upgrade, but ultimately decided against it. Digital thermostats often have compatibility issues with older RV air conditioning systems. I wanted something simple, reliable, and compatible with my Coleman-Mach AC unit.
Honestly, my first reaction was relief. I wasn’t expecting a work of art. The Coleman-Mach 70-8890 Wall-Mount Analog Thermostat Heat/Cool promised to restore some semblance of comfort to my camping adventures.
