home appliance acting up

Does it sound natural to say that a home appliance is acting up? For example:

The TV is acting up again. (The TV set is still working, but there are days when it automatically turns off every 30 minutes for no reason, so you turn it on again.)​

The electric fan is acting up again. (The highest is 3 and the lowest is 1. But when I press 3, it's the reverse. It seems 3 is the lowest and 1 is the highest. But this happens once in a while.)​
