My motor for my kohler air tub stopped working. Who can i contact to have it repaired. I did take the cover off the motor and saw that there was a burn mark near the transformer connection. We did have a storm around the same time it stopped working, maybe aa power sure?

I don't know this specific tub, but here's the pictoral. The button (90105) should come out of its base, held by friction of O ring. This should allow you to disconnect the pressure line. If you are looking to replace the complete assembly, likely you will need a basin wrench to reach nut (65157).
Here are links to Kohler, specific to this tub.

Air Switch Repair
It sounds like you have a bad air switch located in your motor.
The air switch is what the air hose connects to on the back of the motor or on the box on top of the motor. The other end of the air hose is connected to the air button on the lip of the tub.
This is a latching air switch and when you push the air button it latches to send power to the motor. When the air button is pushed again it opens the latch in the air switch and stops power going to the motor shutting it off.

The chances that is problem you are experiencing is related to the suction cover is extremely remote. The suction assembly doesn't have anything to do with the tub motor operating.
The issue is most likely with the motor not working or the air switch in the motor malfunctioning.
What does the control look like that you use to turn the pump on/off?
Is it an air button or an electronic switch?

The problem you are experiencing tells me that the air switch in the motor most likely the problem.
This is a latching air switch that operates when the button on the side of the tub is pushed.
The replacement TBS-339 air switch is around $21

yes. that clear hose goes onto the air switch on the back of the motor. once that is hooked up if you push the air button then the pump should turn on/off for you.

What you need is a new air switch for the back of the motor. The air tubing connects to it on the motor. that is probably what is clicking when you push the air button on the top of the tub. Once you change that air switch you will be back in HOT WATER !!
Should be a TBS-310 or TBS-301 latching air switch is the one you need. Either of those models will work in a Kohler pump.

Check for an air switch at your local hot tub store

take the old one in so they can match it up to a new one

Most of the control buttons on a tub are not electrical. These buttons are connected to an air line that runs to the motor. Sometimes an aggressive button push can literally blow the air line right off of the bottom of the button.
This problem is as easy to fix as it sounds. Find the loose air line and push it back onto the button. You will need to open up your access panel. Bring a flashlight.
Be sure to check the connection at the motor too. Good luck

This is a problem common to all whirlpool/air jet style tubs. The pumps become air locked due to the water evaporating from lack of use. All tubs need, and have, SOME means of priming the pump, this is most likely what the problem was, originally, for you. This time in particular you found it to be electrical in nature but for future reference, for you and all who have these style of tubs, I am putting this out there. Some where on the tub, usually along the top edge of the tub is a vent knob that controls the amount of air that the pump is allowed to mix with the water for the jets, usually by closing this valve all the way (tub needs to be full of water of course) and running the pump for a minute or 2, you should be able to get the pump pumping water again, if not you may need to do something else with your particular set-up to get it purged of air, the pumps in jacuzzi tubs are designed to pump water, not air, so if the motor is running but you get no jet action, your most likely air locked and need to prime pump/purge air.
