Sign up for 521099 RV Furnace Water Heater Fan Control Ignition Circuit Board – Fits Suburban 12V DC
So your RV's water heater or furnace is acting up and you suspect the control board?
This little circuit board is the brains behind the ignition and fan control on a bunch of Suburban water heaters and furnaces.
It's part number 521099, and it crosses with 232613 too, so if you've got one of those, you're in the right place.
It runs on 12V DC, which is standard for most RV setups.
The brand is unbranded, but it's built to replace the OEM unit – not some cheap knockoff that'll fry in a month.
It's brand new, not used or refurbished, and it comes in packaging (though maybe not fancy retail box, but who cares, right?
).
One thing to note: California Prop 65 warning is on this, which is on basically everything these days, so don't let that scare you off.
It's a direct replacement type, so if your old board is fried, this should pop right in with the same connectors and mounting holes.
No UPC on this one, but the manufacturer part number is clear – 521099.
If you've been dealing with intermittent ignition, no spark, or the fan not kicking on when it should, this board is likely your fix.
It's a cheap part compared to replacing the whole water heater, and it'll get you back to hot showers and warm nights in no time.
