| There should be, but I haven't dealt with the factory installed ones. Factory one wasn't even an option for me...I went aftermarket and I can have my truck run for as long as an hour since it is a diesel....mine is currently set at 20 mins. Is there nothing in the owner's manual? There has to be a way to make yours stay running longer though unless it is a physical timing circuit....and even then, you could change it and let it run longer.
