Three out of the four fans in my home, when turned on; speed up to the highest level and the lights turn on randomly. The fans are all the same Hunter brand, but one of the fans is a different model, all are turned on by remote control. How do I fix these fans to run properly?

Change the frequencies of the remotes and receiver. Each fan and remote set should match but not match the other fans.
