What to do if Alto-Shaam 750-SK shows under-voltage error?
If your Alto-Shaam oven displays an under-voltage error, it indicates that the supply voltage is incorrect. Correct the supply voltage to fix the problem.
Why is my Alto-Shaam 750-SK showing unit over temperature?
If your Alto-Shaam oven is showing a unit over temperature error, it's because the cavity sensor has been over temperature for too long. This could be due to: 1. The cooling fan not operating. 2. Installation clearance requirements not being met.
Why is my Alto-Shaam 750-SK Oven showing unit under temperature?
If the Alto-Shaam oven displays a unit under temperature message, this is due to the cavity sensor being under temperature for too long. In this case, you should troubleshoot the heating elements.
What causes PCB over temperature in Alto-Shaam 750-SK Oven?
PCB over temperature in your Alto-Shaam oven means the PCB board temperature sensor is over 70° C. This can be caused by: 1. Cooling fan not operating. 2. Installation clearance requirements not met.
What does it mean when the Alto-Shaam 750-SK cavity probe is shorted?
If the cavity probe is shorted in your Alto-Shaam oven, it means a short circuit has been detected on the sensor wires, and this will halt any active program. The issue may be with the sensor connection, the sensor itself, or the control board.
What does it mean when the Alto-Shaam Oven cavity probe is open?
If the cavity probe is open in your Alto-Shaam oven, it indicates an open circuit has been detected on the sensor wires, which will stop any active program. Check the sensor connection, the sensor itself, and the control board.
What to do for Probe 1 short circuit in Alto-Shaam 750-SK Oven upper compartment?
If your Alto-Shaam oven displays a 'Probe 1 short circuit, upper compartment' error, it means a short circuit has been detected on the sensor wires. Check the sensor connection circuit in the upper compartment, the sensor compartment itself, and the control board.
What to do for Probe 1 open circuit in Alto-Shaam 750-SK upper compartment?
If your Alto-Shaam oven displays a 'Probe 1 open circuit, upper compartment' error, it means an open circuit has been detected on the sensor wires. Inspect the sensor connection circuit in the upper compartment, the sensor compartment itself, and the control board.
What to do for Probe 1 short circuit in Alto-Shaam 750-SK lower compartment?
If your Alto-Shaam oven displays a 'Probe 1 short circuit, lower compartment' error, it indicates a short circuit has been detected on the sensor wires. Check the sensor connection circuit in the lower compartment, the sensor compartment itself, and the control board.
What to do for Probe 1 open circuit in Alto-Shaam 750-SK Oven lower compartment?
If your Alto-Shaam oven displays a 'Probe 1 open circuit, lower compartment' error, it means an open circuit has been detected on the sensor wires. You should inspect the sensor connection circuit in the lower compartment, the sensor compartment itself, and the control board.
