I bought a 400 watt fogger from Michaels and need a timer. I bought what I thought would be a compatible one from Target. The timer will run the fogger in manual mode, but the fogger won't run on the timer setting. I monitored it for about 10 minutes and it never went! I want to buy the timer local if I can, since buying a gemmy timer online is about $30 shipped right now and is more than I paid for the fogger. I live in Salt Lake City if anyone knows of a location. Is this timer defective or incompatible with my fogger?
