Hi there, may I suggest...if the plug is like a power pac -not a regular cord -- the plug when pulled, may have been
"dropped" to the floor -- there is a way to open the power pac -- there is a small 'fuse" in it --- it could be bad. Check
it. It is possible that the "fuse" is dead. So you may just have to replace the fuse.
As a reminder,the power pac plugs should never be dropped to the floor. Gently set them down.
Good luck. fuzzymom
