b4 calling out the fitter can anyone help with this issue, my 3 way fridge on my bailey champagne 1993, works on both gas and mains elec, however on getting on site i have to first freeze the unit using gas first. then after about half hour i can turn off the gas and it runs for days and days on mains hook up alone, it will not get cold by using mains only when first on the site??? what gives? any help will be appreciated, the fridge was checked 14 months ago and was working fine all last year.
