You shouldn't be playing with machines like this. Professional equipment needs professional servicing.

Standby Mode deactivates the beater and keep the ice cream cold. When you come off Standby, the ice cream warms a little and the beater starts. You can be in standby Mode as long as you like, It keep the ice cream mix in peak condition. There will be a short delay in serving the next customer.

Standby (US and Canada Only) During long no-sale periods it becomes necessary to warm product in the freezing cylinder to approximately 35°F to 40°F (1.7°C to 4.4°C) to prevent overbeating and product breakdown. When the STANDBY button is pressed, the light comes on, indicating the cylinder temperature retention system (CTR) has been activated. In the Standby mode, the Wash, Pump, and Auto functions are automatically canceled. The Mix Ref function is automatically locked in to maintain the mix in the cabinet. To resume normal operation, press the AUTO button. When the machine cycles off, product in the freezing cylinder will be at serving viscosity.

Absolutely! The Taylor 754 and Taylor 794's are capable of 284 3 1/2oz. servings per side / per hour. The 8756 is capable of 426 of the same 3.5oz. servings. The 8756 packs more air into the product making it easier to freeze and reducing recovery time.

In standby mode, the machine just wants to keep the product refrigerated until it goes back into auto.

So, the mix cabinet needs to keep the product cool in the bottom of the machine, that requires the mix compressor and fans to run. The mix cabinet temperature is read by a thermistor probe and regulated by the (left side) logic board.

The product in the cylinders should go back to liquid form in standby, but we still have to maintain that safe food temperature, the motor and compressor will run periodically. If the machine is air-cooled a fan will run anytime the compressors run. If it is water cooled, water will flow through the machine when the compressor runs. The temperature in the freezing cylinders is read by a different thermistor probe and regulated by the logic boards.

I don't think you have a problem... I have a Taylor 8756p-27. In standby mode with my unit the beater motor turns on for about 15 seconds every 15 minutes and the compressor turns on as needed to keep the mix at a safe temperature. This is what standby mode is supposed to do. If you don't want it to turn on and off so much in standby mode, perhaps leave it in AUTO mode and it will turn off and on as it needs to to keep your product at the proper temperature.

too hard to explain online, you need to contact your local taylor dist. or a local service company who might install or know about them.

if the product is frozen in the barrle for sure then you have a bad micro switch that is telling the compressor to keep running, but that product would be super frozen and come out in the shape of the barrel. if it is the consistancy of ice cream then your pump gasket might be bad and not properly pressurizing your barrel and giving you the impression of a frozen barrel.

This seems like it could be many things. Is the pump coming on when you try to dispense? Can you stick a thin wire up through the feed holes in the chocolate side when you try to dispense to help free the product?

That is most likely the stand by probe. The standby thermistor probe measures the temperature of product, in this case in the freezing cylinder, while the machine is in standby. Usually when the thermistor fails, you come in in the morning to find that the product is liquid and the reset has been tripped. The motor should be nowhere near the overload setting in standby as the product should be liquid. Thermistor probe C712 C713 Barrel Stanbye Probe

That's a low mix light. It tells you that you don't have very much ice cream mix left in the hopper. There is a sensor in there that when no mix is touching it, it turns that light on.
