What should I do if the backlight and fan of the CATA TFH 6630 X hood do not turn on while the sensor is working?

Question

Accepted Answer

If the LED backlight and fan of your CATA TFH 6630 X refuse to turn on while the sensor is functioning, this indicates a problem with the touch control panel or the electronic power supply. Here are the diagnostics to perform in order:

Step 1: Check the power supply

Ensure that the hood is receiving a power supply of 220-240 V, 50 Hz as per the model TFH 6630 X nameplate.
Check that the circuit breaker related to the hood has not tripped. If it has, reset it and wait a few seconds before testing.
Completely unplug the hood for 30 seconds, then plug it back in. This action resets the electronic system.

Step 2: Test after electrostatic discharge

According to the technical manual of the TFH 6630 X, an electrostatic discharge (for example, during a thunderstorm) can stop the hood without causing damage. If you suspect such a phenomenon: unplug the hood from the electrical outlet, wait at least 1 full minute, then plug it back in and test the touch buttons.

Step 3: Check the control panel and initial setup

Press the Light On/Off button once only. The icon should light up red and the LED should turn on independently of the fan.
Press the Fan (speed reduction) button once. The hood should start at speed 1. All icons should light up white and the LED will display the speed number.
If no system responds, it means that the electronic touch panel is not registering commands. The buttons may be defective or the electronic circuit disconnected.
Check that you have not just performed the initial setup by pressing both speed buttons together (this operation must be done within 2 minutes of powering on).

Step 4: Check the filter and internal connections

Ensure that the grease filter (washable aluminum) is not excessively saturated. A filter that is too dirty can trigger the saturation indicator and disrupt operation. Clean it with hot water and a cleaning product.
Visually check that no internal connection is unplugged (especially the cable connecting the control panel to the power supply system of the fan and LEDs).

If after these checks the backlight and fan still do not activate, the problem lies with a failure of the touch panel, power electronics, or a broken internal connection. Contact a qualified technician or an authorized CATA service center for a thorough diagnosis and repair.
