Guaranteed to work upon receipt. If it does not work you may return for a full refund. The remote number is usually not the same as the model number of the unit that you are trying to operate. The first number in the title is the remote pictured. The other numbers in the title are for (OME) Original Manufacturer Equipment model numbers that are compatible. If not listed, please verify that this remote is compatible with your unit. If you do not see your model number, please eBay message me to see if I have what you need. I have a 95% success rate in locating your remote. I do test each remote and every button when listed and before shipping.
