Strange Noise

[TN Bill]

I have a 2004 Winnebago Brave on a Ford Chassis. The MH has been parked in the car port for 3 weeks and not run. Last night I heard a sound ant best I can describe it is WA, WA, WA, WA. It make it exactly 4 times and does it every 5 minutes and did it all night. This has hapened before, last winter in Florida, and I just ignored it. Any ideas?

Could it be temperature change causing air to go in or come out of the radiator? It was hot here yesterday.

Could it be a low battery warning signal of some type? Never heard anything like that. Our smoke detector emits a high pitched beep periodically when battery needs replaced. You might want to give the Winnebago customer support folks a call on that one.

Good luck and let us know what it was
