### ⭐⭐⭐⭐⭐ Used this transformer in Stem kits before with no issues.
*by T***K on 4 August 2026*

I am changing my one star review to a five. The issue below was caused by me connecting two transformers to a common 24 VAC output, wiring error on part. After attaching 120 vac to the whittle and black wires for 120 vac input and the 24 vac output. Without any loads attached to the 28 vac leads the transformer heated up and failed with smoke and the smell of burnt electronics. I’m still debating if I did something wrong or it was defective.
