Hi, How old is the unit? Is there a warrenty on it. If so, anything you do to it may void the warrenty. First, check to make sure breaker on the end of the plug is not tripped. It will probably have a reset button on it. If it will not reset it can be replaced with a regular 110 plug if needed. (If this is a 110 unit) If you are talking about the control panel on the AC when you say control box I think you are getting into more than you can handle and not sure that what you ordered is even what you need. If you want to get into it, first make sure it is unplugged, Take off the front cover and slide the unit from the outer cover, there may need to be a few screws removed to do this. Look at the wiring and see if there is anything burned or loose. Other than this you would have to get a meter and talk with someone on here familiar with your particular unit to troubleshoot it. I really don't think you should order any parts before you find out what the problem is. If there isn't anything that you can see that's wrong with it I would suggest taking it to Sears and letting then determine if it would be better to fix it or replace it. Hope I have helped. kstfas

I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........
In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.
Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.
Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)
Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.

Hello & Welcome to FixYa
PF error means power failure which is generally caused when the control board inside the unit goes bad. You can try unplugging the unit for 15-30 minutes, if the issue returns then the control board needs replacement. Please get back to me if you have any other questions.
