Review on 🚪 MM271 Automatic Gate Opener by Mighty Mule - Single, Black by Shane Ryder

Previous Mighty Mule Gate Openers used an 18VAC transformer. In fact, the user manual for the MM271 states that the output of the transformer is 18-22 VAC. Imagine my surprise when I measured the transformer output voltage as 40VAC. I called tech support and after 30 minutes of waiting with horrible repetitive music (?) spoke to the helpful phone person. He agreed the output should be 18VAC and arranged for a replacement and RA to be sent. The new transformer had the same readings (40 VAC) as the first. Let's get back to the phone and the mandatory 30-minute holds. This time I found that the output of the transformer should be 18V DC not AC and that the user manual was wrong (as was the original technologist answer). I changed the voltmeter settings and both transformers read 18V DC. I've been told I can keep the extra transformer, but I will never get the time spent back.
