Pulled off a job where the generator itself failed, the control worked fine. It's a 4 pin connector, I have included the proper cable. Even if your existing control has a 3 pin cable, as long as the end that plugs into the generator looks like the one in the last picture you are good to go.

This will replace all Smart controls, 2 button, 3 button and the large Smart Plus that has 5 buttons and 2 scales for time and temp. This is a simple On/Off.

The finish is worn, the decal is new, it will get the job done if your generator is still good. Better than replacing the entire system for $4-5000.

No returns on these parts, you must have an authorized Mr. Steam agent test and install to make sure this is what you actually need. If you install it  and it still doesn't work that means the generator is bad, so get it tested FiRst!
