F1 The F1 error on a Monogram range indicates a faulty oven temperature sensor (RTD probe) or a problem with the electronic oven control board. The sensor may be reading out-of-range resistance values, triggering a safety shutdown. Range High F2 The F2 error on a Monogram range means the oven has exceeded its maximum safe temperature limit. The control detected temperatures above approximately 590°F (310°C) during baking, broiling, or a self-clean cycle and has shut down the oven as a safety measure. Range High F3 The F3 error on a Monogram range indicates the oven temperature sensor circuit is open — meaning the sensor has broken internally or its wiring has an open connection, and no resistance reading can reach the control board. Range High F4 The F4 error on a Monogram range signals that the oven temperature sensor circuit is shorted — the sensor or its wiring is sending a resistance value far below normal, which the control interprets as an abnormally high temperature reading. Range High F5 The F5 error on a Monogram range indicates a door latch fault. The control board is not receiving the correct signal from the door latch switch, most commonly during or after a self-clean cycle. The door may be stuck locked or unable to lock. Range Medium

Code Appliance Meaning Severity

CC Beverage Centers The CC code on a Monogram beverage center indicates a compressor control fault. The control board cannot start or communicate with the compressor, resulting in no cooling and stored beverages warming toward room temperature. High View details → dE Beverage Centers The dE code on a Monogram beverage center signals the door has been open for an extended period — typically two or more minutes. The alarm notifies the user to close the door to prevent warm air infiltration and temperature rise in the beverage compartment. Low View details → HI Beverage Centers Error code HI on the Monogram ZDB undercounter beverage center indicates the compartment temperature has risen above the acceptable upper threshold. On a beverage center designed to chill drinks to optimal serving temperatures, a HI fault means beverages are warming and the cooling system is not performing as required. Medium View details → PF Beverage Centers Error code PF on the Monogram ZDB undercounter beverage center is a power failure notification displayed after the unit has restored operation following an interruption in its electrical supply. The PF code informs the user of the outage event and prompts a check of compartment temperature and beverage condition following the power interruption. Low View details → tC Beverage Centers The tC code on a Monogram beverage center (ZDB/ZDW series) indicates the temperature sensor (thermistor) in the beverage compartment has failed or is producing an out-of-range signal. Without a valid temperature reading, the control board cannot regulate beverage cooling. Medium View details → CC Column Refrigeration The CC code on a Monogram column refrigeration unit (ZIR/ZIF) signals a compressor control fault. The control board cannot start the compressor or the inverter drive for the variable-speed compressor has reported an internal fault, halting the cooling cycle entirely. High View details → dE Column Refrigeration The dE code on a Monogram column unit (ZIR/ZIF) indicates the column door has been detected open for an extended period — typically two minutes or more. The full-height door is ajar, improperly latched, or the door sensor has malfunctioned. Low View details → FF Column Refrigeration The FF code on a Monogram column refrigerator (ZIR series) or column freezer (ZIF series) indicates a failed defrost cycle and frozen evaporator coil. Ice has accumulated to the point of blocking airflow, preventing effective cooling of the column unit. High View details → HI Column Refrigeration Error code HI on Monogram ZIR column refrigerators and ZIF column freezers indicates the compartment temperature has risen significantly above the set point and beyond the acceptable upper threshold. This typically signals a cooling failure, excessive heat load, or a refrigerant system issue requiring immediate attention. High View details → PF Column Refrigeration Error code PF on Monogram ZIR and ZIF column refrigeration units is a power failure notification. It indicates the unit detected an interruption in its power supply — such as an outage, a tripped breaker, or a voltage sag — and has now restored operation. The code serves as a historical alert rather than an active fault. Low View details →
