Fast shipping. This transformer works like any oem one for 240v systems. If you don't have 24v to your thermostat, It is probably the transformer. This went into an Allied Air handler.

I bought this Lusperi 240V to 24V Transformer after installing my Ecobee Smart Thermostat, and it was exactly what I needed. I was confident that I had installed the thermostat correctly—I quadruple-checked everything and watched countless videos before even starting the upgrade. But then, suddenly, the entire HVAC system lost power, and I couldn’t get it to come back on, even when I tried reinstalling the old thermostat. The system was dead by all accounts.At that point, I thought I had broken something serious, and I started to panic. After doing some more research, I discovered that the transformer might be the issue, possibly “blown” from the upgrade. I ordered this replacement transformer, and once it arrived, I followed a few simple steps to install it. After flipping the breaker back on, everything powered up perfectly!Installation Instructions (Simple Steps):Turn Off Power – Before starting, turn off the power at the breaker to avoid injuries or electrical issues.Locate the Old Transformer – Usually, it’s near the furnace or AC unit. Disconnect it carefully and remove it from its mount.Connect the New Transformer – Match the wires according to your system. Make sure everything is securely connected.Turn Power Back On – Flip the breaker back on, and if everything is connected correctly, your system should come to life.Final Thoughts:This whole experience taught me it wasn’t an installation mistake—it was just the old transformer reaching the end of its life. The new thermostat likely put a little more demand on it, and that was enough to push it over the edge. Since replacing it, my system has been running flawlessly. I even bought an extra transformer as a backup, just in case.If you’re experiencing similar issues, I highly recommend giving this transformer a try. It’s an easy fix that brought my whole setup back to life!
