My tumble has been blowing cold air, and I cannot understand why!
It sounds, smells and looks fine when turning, except its cold. I have checked all the vent bits that are removable or easily removable with a screwdriver, nothing seems amiss, or blocked. No lights come on to suggest an issue. It’s 6 years old, but not heavily used so it feel early for it to give up the ghost!
hoping someone can provide suggestions before I cave and call someone.
thank you!!
