While cleaning inside my cabinets, I discovered that my cooktop has been leaking some kind of grease or oil for what looks like a decent period of time. The substance (now removed) left a thick orangey/brown trail out of the motor/blower wheel connection and down the vent duct. The consistency was similar to Crisco. I thought it might be a gap where the parts meet allowing grease from the fan vent to accumulate and then leak, but my husband suggested it might be motor oil, which I assume is a much bigger problem. I believe the leak occurred where the motor cover meets the blower wheel cover, but I am not sure of my part names. I was thinking of sealing the small gap with a silicone caulk, but if I have a motor problem, I will of course hire a pro. Thanks for any advice you might be able to give.
