What to do if the beater motor runs but the compressor doesn't in my Taylor Freezer?
- Y
  Yvonne ThomasJul 27, 2025
  If your Taylor Freezer's beater motor runs but the compressor doesn't when the power switch is in the AUTO position, there might be several reasons. First, the internal overload in the compressor may have tripped; allow it to cool and check for high head pressure, refrigerant overcharge, stuck pistons, or tight bearings. Alternatively, the compressor itself could be burned out, requiring replacement. Other potential causes include improper compressor wiring (check against the diagram), low line voltage (check at the terminal block and find the source of the voltage drop), or a single-phasing compressor contactor (which would need replacement).

How to troubleshoot a Taylor Freezer that won't turn on in AUTO mode?

  If your Taylor Freezer isn't operating when the power switch is in the AUTO position, here are a few things to check: * Make sure the unit is plugged into the wall receptacle. * Check the fuse and replace it if blown, or ensure the circuit breaker is in the ON position. * If the beater motor is out on reset, place the control switch in the OFF position, press the reset button firmly, then place the power switch in the WASH position to observe performance before resuming normal operation.

Why does my Taylor Freezer keep short cycling?
- R
  Renee PetersonAug 4, 2025
  If your Taylor Freezer is short cycling, it might be due to cycling on a high pressure cut-out. For 404A refrigerant, the cut-in pressure is 340 PSI (2,344 kPa) and the cut-out pressure is 440 PSI (3,034 kPa). Check the water supply if you have a water-cooled unit and ensure the condenser is clean. Also, check for potential refrigerant overcharge.

What to do if my Taylor Freezer compressor hums but won't start?
- M
  Mr. Samuel MedinaAug 9, 2025
  If the compressor in your Taylor Freezer hums intermittently but won't start and is cycling on overload, start by checking the wiring against the diagram to ensure it's properly connected. Also, check the main line voltage to locate any voltage drops. Finally, inspect the relay contacts to see if they are closing; try operating them manually and replace the relay if it's defective.

Why is the product from my Taylor Freezer too stiff?
- D
  David StoutAug 13, 2025
  If the product from your Taylor Freezer is too stiff, the viscosity control might be set too high. Refer to the Torque Control section to reset it. Also, check if the Torque Assembly is incorrectly assembled by consulting the Troubleshooting Torque Components section. Finally, ensure there is an adequate mix in the hopper by filling it with the mix.

Why is the product from my Taylor Freezer too soft?

  Joel WatsonAug 18, 2025
  If the product coming out of your Taylor Freezer is too soft, it's possible the viscosity control is set too low. Refer to the Torque Control section to reset the control.

What causes low head pressure in my Taylor Freezer?
- Z
  zamoraaaronAug 22, 2025
  If the head pressure in your Taylor Freezer is too low, it could be due to a shortage of refrigerant. Locate and repair the leak, then recover the refrigerant, evacuate the system, and recharge it. Another possible cause is a water valve stuck open (if it's a water-cooled unit); clear or replace the valve.
