Good day, I do not believe in vacuuming the coil. Due to the thickness of the coil, it should be blown out. If You do not have an air tank and hose, a good shop vac with a push-pull feature, and a crevice tool is a good substitute. It's messy and filthy, but is the only correct way. The light comes on when it senses high discharge temperatures or excessively high compressor running time. If cleaning fails to resolve the problem, call for service. It may be a refrigerant leak just starting, a serious problem.
