This is usually caused by a dirty condenser coil or a stalled condenser fan.
Remove the cover from the rear of the fridge and see if the fan is running. If not, make sure nothing is stuck in the blades keeping it from turning. If it turns freely you probably need a new fan motor but you would need to check the voltage to be sure.
Post back if you have any questions.

Hi,Your husband did good job, after cleaning and vacuuming, did freezer (bottom) have excessive ice?, if there's excessive ice in bottom, after cleaning, you have a defrost problem, but if there're no ice in freezer after cleaning, you got freon (gas leak) , there's a condensate loop, that passes through ref. body, from compressor that naturally develop, freon leak after few years, by rusting, normally it can be by- pass. vacuum and refill with freon, if there's no freezing, but compressor running, you'll need a mechanic, you got a freon leak. good luck.
