I purchased a Home Trends low mount ceiling fan from WalMart about 5 years ago. My father and I installed it. It is a model that has a remote control which turns on the light, dims the lights, and has 3 speeds for the fan. It worked great until last fall. At that time, I noticed that it was more and more difficult to get the remote to turn on the fan or change the speed. Now the remote has stopped working completely. I have replaced the batteries in the hand held remote, changed the wall socket switch, tried pulling on the chains, nothing has caused the fan to come on.

I faintly remember us installing a 9V battery up in the guts of the ceiling fan. Does anyone know if this is the case, and if so, where is it and how difficult would it be to replace? I've searched around the base, looked into the vent openings on top, and don't see a battery anywhere. Anyone have an idea?

never seen a battery in fan, receivers are usually powered by the 120 volts. I would write down the dip switch code(124 on, for example. Then move the switches back and forth a couple of times, then try with the code you wrote down. If there is a possibility of switches in wrong position. Instead of going to the fan canopy and seeing what the receiver code is, I would go through the 16 codes, binarily counting.
The 16 possibilities are:
0001
0010
0011
0100
0101
0110
0111
1000
1001
1010
1011
1100
1101
1110
1111
0000
1= switch on.

Never heard of a 9V battery in a fan. It wouldn't be necessary, the fan gets power from the supply.

Check the dip switches as Strat mentioned, or the receiver could be bad.

5 years out of a WalMart fan is pretty good

The receiver is quick to get zapped with any major power fluctuation. I lost one in the Home Trends Style 14441 a few years ago, and just took an indirect lightning strike and lost another one. The number for HomeTrends in the Walmart manual is no longer a good number. I have been trying to get a phone number for HomeTrends to get the replacement part, but have been unsuccessful. I am going to see if I can get a remote and receiver from Home Depot or Lowe's and make it work.
