My pump is not starting when high-speed is selected to turn on the pump. The pump makes a loud buzzing sound when trying to start the pump and then the thermal cutoff switch shuts the pump off after a few seconds of trying to start. The pump makes the same noise when starting on low-speed, but it does start after a second or so of the buzzing. I replaced the capacitor and it still has the same symptoms.
The pump is connected to an Intermatic T-104 and T-106 timer/switch and once the pump is running it has no problems switching speeds with the T-106 switch.
The pump has always been on the loud side and at times the bearings sound like they need replacing then an hour later the pump sounds normal.
Any recommendations on what I should look at next? Pump specs are in my signature.
