KING KB2415-1-B2-ECO KB ECO2S Garage Heater w/Bracket, Thermostat and Remote Control, 15000W / 240V, Gray

I bought this garage heater because it was Made in the USA. I have had it since January 2021. Today, without warning, I found the garage full of smoke and the garage heater displaying 99 on the front panel. I turned off the breaker to the heater and shut it down. There was nothing else in the garage that was smoking, just in case that is someone's question. I had the heater professionally installed by a qualified electrician. I called Technical Support and the person who answered said I had to call another number. I called that number and it always goes to voicemail. No one ever answered. I called again and got customer support and asked what "99" meant on the front of the unit. The only answer I got was they were not in technical support and could not answer that question. This is an absolute piece of junk and I would not recommend that anyone purchase any heaters from King.
