So I went to turn on the exhaust this morning and it didn't work. After pressing the button twice there is a delay of 5 seconds and it will flash twice and then go off. The exhaust doesn't open at all.

I have no Bluetooth devices on as I know this can cause intermittent issues. The only thing I can think of is the very cold weather (-2c). Would this have an effect on the exhaust electrics?

How long is the warranty on the exhaust? I've had it for 10 months now with no problems.
