Troubleshooting the E-210 Cooling Fan Failure

Overview

If one of the two fans at the top of the UHC 600 is detected as not running, an E-210 error is triggered.

Perform these steps first to avoid travel to the restaurant, reducing cost and adding value for your customer.

1. Ensure the louvers at the bottom sides are free from obstruction, dust and debris.

2. Ensure a clearance of 1.5 in (38 mm) is held at sides, top and rear from other equipment.

3. Remove any nearby heat source causing hot air to get pulled into louvers.

4. Turn the main power switch off for a few moments, and then turn it back on. Wait. If the issue doesn't resolve itself, continue the troubleshooting steps below on-site.

Field Troubleshooting

To avoid electrical shock or property damage, disconnect power before installing or servicing equipment. A qualified technician must perform the service procedures.

1. Unplug main power to unit and turn main power switch to off position.

2. Remove the top cover of the unit to gain access to the electrical components.

3. Reconnect power and turn on the main power switch.

Note: At power up, fans energize for about 2 seconds and pause for about 20-30 seconds then energize again.



4. Determine which fan is not running or running slowly. If 12VDC is supplied to the fan that is not running, replace fan.

Note: Voltage can be checked at the test points at the connector of the fan.

NOTICE -

To avoid product damage, ensure the I/O board is completely disconnected from power when connecting harnesses. Voltage spikes can damage the I/O board. No lights should be illuminated or flashing on the I/O board.

5. If 12VDC is not detected, or fans have been replaced with a known good fan, but the error remains, replace the I/O board.
