Your start capacitor is probably cooked. It is replacable ... but be careful ... it MIGHT still be charged when you remove it.

My husbands Yamaha Royal Star will completely stall while riding. Any ideas?

Make sure you have fuel getting to the carb/injectors. If you have fuel and you say you fiddled with the ignition switch and it worked, you might need a new ignition switch. I hope this helps. Rod

How long after plugging in fridge should compressor start ?

It should start up within a couple minutes. the electronic control board controls the compressor as well as all the other functions of the refrigerator. If the refrigerator is cold when you plug it in then it may not start right away but opening the doors for a few minutes should get it to start up. If it doesn't come on after a few minutes the control board may have issues.

The bottom of the refrigerator and near compressor is where the condensate drains to. The condensate begins in freezer during defrost and collects in a collection tray behind rear wall of freezer and with a drain hole and pipe that feeds through the cabinet and down to drain pan where it is warmed by the compressor heat and returned to the air inside your home. The only way to really get a good look at pan is to pull the refrigerator away from wall and remove cover over the compressor are. I recommend unplugging first before placing hands inside.Thanks, Sea Breeze

Refridge quit cooling suddenly inboth freezer

That could be a broad range of possibilities. The defrost timer, adaptive defrost board,compressor start relay, compressor start capacitor or a mother board. Would you happen to have the model number so I can narrow down those possibilities? If you pull away from wall remove cover over the compressor and then unplug. Touch the compressor and let me know if cool, warm or too hot to touch. Thanks, Sea Breeze

Since the overload was good when tested, check also the electric current if the current is in the right voltage.
If the problem still a raise, it is now the motor compressor that have problem. The motor it self cannot start or hard starting.

The compressor just seized, so I just bought a new much more efficient unit.

Freezer has quit working and now refrigerator not cooling like it should.

If you hear the start relay clicking after the compressor tries to start then you know that there is power to the compressor.
This tells you it is ether a bad start relay or a bad compressor.
At this point I use a meter to see if the compressor is shorted to ground.
If the compressor is not shorted then replace the start relay and give it a try.
You should hear the compressor start right away with a new start relay if that was the problem.
If the compressor is shorted to ground you will need to have the compressor replaced.
Given the history on whirlpool refrigerators in the 5 year old age range It may be good chance that a new start relay will fix your refrigerator.
If the start relay is bad you will hear it try to start the compressor and then click off.
If the relay is bad you will hear the clicking sound seconds after plugging it in and then again every minute or two as it keeps trying to start the compressor.
