Perfect match

This thermostat is also a perfect replacement part, as in OEM, for my 20 year old Marley engineering FZL4004B forced air wall mount heater. The control knob much improved over the original which was always a flimsy design. The unit was well packaged and promptly delivered.

A one time fix for my Wall Heat

I installed the switch, changing the ends on the wall heater was the only thing I had to do.

Quick and easy

My order arrived quickly, in good condition and was exactly what I needed/ordered. That's a perfect transaction in my book. It was also very easy to find on the website which I cannot say for some of the competitors.
