## Customer Reviews

### ⭐⭐⭐⭐⭐ Direct replacement for C340041P04
*by N***P on August 15, 2024*

Needed a replacement for C340041P04 and couldn't find a solid answer online one way or the other, but the voltages all worked out so I gave it a shot. Works perfectly with no issues

### ⭐⭐⭐⭐⭐ Works great
*by K***Y on June 1, 2024*

Transformer easy to install. Central air cranking along great. Part replacement for Trane transformer.

### ⭐⭐ Questionable power output lead
*by J***Y on January 22, 2025*

I purchased 2 of these for overhead garage heaters and one of the outputs is labeled 24V and the other "OV". A little research revealed that the OV stood for Over Voltage but not sure what that ultimately meant. I asked two HVAC professionals about it and they have never seen such a thing on a furnace and recommended I not use. So needless to say I returned these transformers and order a transformer that was OEM for my heaters that had 2 output terminals labeled 24V.
