Taylor Slush Machine Error Code BRL Temp 2 High: Product Over 120 F

What does Taylor BRL Temp 2 High mean?

A frozen drink should sit near freezing, so a barrel reading above 120 F (49 C) is far outside its range. The C300 control watches the barrel temperature in every mode, and when it passes 120 F it shuts the entire machine down as a protective stop. The display shows BRL Temp 2 High. This is more serious than a cylinder that simply fails to cool, because something may have been adding heat, and a heat input that failed to stop may do it again. The manual's reasons include a thermistor that reads the product temperature wrongly, a heat or defrost function that did not switch off, a control board that fails to end the heating, and product left warm after a cleaning or heat cycle. The product is treated as unsafe, and the machine should not be restarted until a technician has found out why the barrel got that hot.

Affected models and control systems

Taylor Model C300 frozen carbonated beverage / slush freezer; the limit applies in any mode and shuts down the whole machine.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• BRL Temp 2 High is shown and the entire machine is off
• The product in the barrel is far warmer than a frozen drink should be
• The control does not restart on its own

Possible causes

Listed in Taylor's documentation

• A thermistor that reads the product temperature wrongly
• A heat or defrost function that did not switch off
• A control board that fails to end the heating
• Product left warm after a cleaning or heat cycle

Other likely causes — what usually sits behind BRL Temp 2 High on this control. A technician confirms which one it is before any part is replaced.

• A heat cycle started for cleaning and left running because the end signal never arrived
• A thermistor probe displaced so it reads far above the real product temperature

Safe checks before calling for service

How a technician diagnoses BRL Temp 2 High

1. Read the screen and ask what mode the machine was in at the stop.
2. Compare the thermistor reading with a calibrated thermometer in the barrel.
3. Check the heat or defrost circuit to confirm it is off.
4. Inspect the control board output that drives heating.
5. Verify the barrel cools and holds temperature on a test run.
6. Replace the thermistor or board only after the test.
