1322410A Webasto Thermo 90 Flame Detecter 24V replace

Compatible Flame Detector 1322410A for Webasto Thermo 90 24V – Replacement Flame Sensor (No More “Flame Out” Tantrums)

Real talk: nothing kills the vibe faster than your Webasto Thermo 90 deciding to shut down mid-winter because it “lost the flame” and now you’re sitting in a rolling icebox wondering who you pissed off in a past life. You restart it, it tries once, twice… nope. Fault light blinking like it’s laughing at you.

That flame detector (the little snitch that tells the controller “yep, fire’s still going”) is usually the one that bailed.

This 1322410A compatible 24V flame detector is the direct replacement built for Webasto Thermo 90 heaters. It keeps an eye on the combustion flame like a paranoid bouncer – detects it properly, signals the controller, and stops your heater from throwing a hissy fit and shutting down for no reason.

Why this one doesn’t flake out like the old one:

• 24V locked in – wrong voltage and it’ll probably pop like a bad light bulb (don’t learn that lesson the hard way)
• Ionization-style detection – super sensitive to actual flame presence, no more false “flame out” shutdowns
• Exact fit for Thermo 90 24V – same mounting, same wiring harness plug, no cutting wires or swearing in -20°C
• Swap it in 20–40 minutes (power off first unless you want your cab to look like a mini lightning storm)
• Kills the usual suspects: heater starts then dies quick, random shutdowns, flame failure codes that make you want to punch the dash

Look – it’s not gonna make your Thermo 90 bulletproof forever, but it’ll stop you from wanting to set the whole heater on fire every time it ghosts you. And the price? You’re basically stealing it from the dealer and walking away with a part that actually keeps the flame alive.

Quick facts before you smash buy:

• Part: 1322410A compatible
• Voltage: 24V (check twice or cry once)
• Function: Ionization flame sensor/detector
• Warranty: 1 full year (if it stops talking to the controller, we got you)

Thousands of truckers, RV guys, and guys who basically live in their rigs have thrown this in and gone from “why does my heater hate me?” to “finally warm and not raging at 4 a.m.” Don’t let your Thermo 90 keep pulling the “flame out” card.

Hit Add to Cart before the next deep freeze shows up. Ships fast – faster than your current flame detector ever detected anything.

(And yeah… if you buy it and still get cold shutdowns, blame the weather, not me. I already told you to double-check the voltage 😂)
