We have a Danby air conditioner, model DPAC120068. Yesterday, there was a beeping sound ( air conditioner was operating) and after approximately 7 beeps , I noticed a flashing red light under the symbol that looks like a bucket or popcorn box. What is this indicator light telling me? Is it serious or can it be easily reprogrammed? What does the symbol stand for? Thanks for any help you can give me. Yvonne Duncan
