False „exceeding operating temperature“ alert

Hello there,
wanted to start the first cook of the season this morning, prepped the meat and smoker. However, when firing up the Inkboard BBQ blower 027BW, I got an alert for all three probes just like below.
The device worked just fine last year and the probes are working. Proofed it by replacing the blower with my regular INKBIRD WiFi thermometer.

Turning on/off, removing and adding the device again didn’t help.
Any ideas?

Thank you,
David

Hello,
Just to confirm, is the ISC-027BW connected to the original probes?
Could you please put the probe and probe’s cable (excluding the probe’s plug) in a 150C (302 F) oven for 30 minutes, then test it with boiling water ( please hang the probes and do not let it touch the container). Can it work?

Please note that the cable of the probe (silver wire) is not waterproof. Please do not immerse the cable into the water when washing the temperature probe.
Otherwise, it will show an incorrect temperature if there is water in the cable.
Please do not put the probe/the probe’s cable in the fire or place it in which temperature is higher than 250C/482F. Otherwise, the probe and the cable will be damaged.

If the problem still cannot be solved, please provide the order information and problem description to the email support@inkbird.com.
Please don’t worry, they will provide the next after-sales service.
