WINNEBAGO MICRO MINNIE 1700BH – LP Gas Detector Replacement

Most owners of the Winnebago Micro Minnie 1700BH never replace their LP gas detector until it fails catastrophically—and by then, you’ve already been breathing air that the sensor didn’t catch. These units have a finite lifespan printed right on them, but I’ve pulled detectors out of rigs that were five, six, even seven years past their rated end date. The problem isn’t laziness; it’s that a silent, invisible sensor on a wall inside a cabinet doesn’t scream for attention the way a leaking water line does. But propane doesn’t care about your detection schedule. When an LP gas detector ages out or fails, you lose the one safety net between a propane leak and a very bad situation unfolding in a space the size of a bedroom. I’ve done this swap on the Micro Minnie more times than I should have to, and every time the owner says the same thing: “I didn’t realize it was that old.” This replacement takes an afternoon, costs less than a night in a paid campground, and it’s the kind of job that actually matters when things go sideways.

The Briidea Dual Alarm That Actually Fits the Micro Minnie’s Power Budget

The original LP detector in these Winnebagos pulls power inconsistently and can fail without any warning sign—you won’t know it’s dead until your nose catches something the sensor should have. The Briidea dual LP/CO unit is a straight replacement that operates cleanly off 12 VDC and includes separate LED readouts so you’re actually watching what the detector is doing instead of hoping it’s working.

What works

• The 100dB alarm cuts through everything—engine noise, fan noise, road vibration—you will hear it, period.
• Two separate LED indicators tell you whether you’ve got an LP problem or a CO problem; you’re not staring at an ambiguous warning light trying to decode what’s actually happening.
• Current draw is modest and steady—no battery voltage sag, no weird drain cycles that bleed your coach 12V system dry overnight.

What doesn’t

• The mounting bracket is designed to fit everything generally, which means it fits the Micro Minnie’s mounting location poorly—you’ll need to drill fresh holes because Winnebago’s factory holes almost never align properly; bring a drill bit.
• Watch for loose pins rattling inside the connector housing when the unit arrives—some shipments go out with crimps that didn’t seat properly, so verify your 12V connection works before you close up the wall and drive away.

I second-guessed whether the Briidea’s proprietary mount would clear the fuse panel on my flip unit until I realized the bracket is actually removable and the sensor itself fits any standard RV cutout. Order the Safe T Alert – Mini Dual LP/CO Alarm – Flush Mount Black – and verify the connector seats all the way in before you close up the wall panel.
