I bought 2 hunter ceiling fans model # 20593 with remote. After 6 months the speed slowed in all 3 positions but the bulb lights in one fan. The other fan lost all power, fan does not spin and bulb does not light. What's the problem?

It sounds like someone was pulling the fan and light pull chains.The chains are still active even when running on the remote controls. You need to check the fan to see if it's in high.
