Hi. This ice maker should have a test button. Looks like it is on the bottom left of the head of the ice maker. What happens when you press the and hold the test button? Is there something mechanical holding the ice try from rotating? Theses ice makers are very common to break. Sorry I do not have a tech sheet for this unit. Make sure the door switches are working properly. Try the test button. I would suspect the ice maker. p # AEQ73110203

Hi. I have attached the tech sheet for you. The control board is part of the defrost system. You also, have you heater, fuse and sensor. Test your fuse and sensor for ohms with your mutli meter. The Sensor temperature chart is on the tech sheet. Its resistance will change according to temperature. The control board is not common for this issue , but if your heater sensor and fuse test out good the only part left would be the board. Check your error codes in the diagnostic mode as well.

I cannot seem to get model number rf28hfedbsr02 to come up as a valid model. Please recheck and provide so we can further assist you. Thanks

Hi. It does not sound like the blower wheel if the noise goes away when you run the unit with out the drum. It is possible. Check that your motor mounts are in place. Check the rear drum supports and idler pulley. It could be the front plastic ring bearing, or the rear felt seal. They could be damaged or have something suck in them. IT is also very common for coins and other debris to get stuck in the baffles. I would take the baffles off and clean them out as well.

HI. I did not find a F1 E9 error code in the tech sheet. I think you meant F9 E1 for a long drain error. I have attached the tech sheet for you. Is the water draining out of the machine fast enough? Is the stand pipe that the drain hose goes into. properly set up, with proper height and size? You could have a drain pump that intermittently does not want to work, or a pressure switch or hose issue. Or possibly a CCU problem. Go through the steps under the long drain error in the tech sheet, which leads you to a different page to run some tests. Are there any other stored errors in the system?

hello, that is a shifter fault
Fault is displayed when the main control cannot determine position of shifter.
• Check harness connections from main control to motor and shifter.
• Observe shifter operation.
• See TEST #3a: Drive System–Shifter.

i have attached a tech sheet for you it is not the exact model but very similar. same parts and error codes you will see. Also the tech sheet inside your machine should be on the left wall of the case when you pop the top up. this tech sheet will show you how to do that.

Hello, i would check to make sure the drain line is secure, it may be flopping around making noise. If you are sure all things are secure and isolated it to the tub itself then you may have a broken part on the inner tub. you would need to split the tub apart to be for sure. it is a very intensive and expensive repair.

Hello, unfortunately if the compressor is running and you have no frost pattern on the coils you will have a sealed system leak. When you have a sealed system issue you need to have a EPA certified tech come out to diagnose and replace or repair the leak. It can be a real pain to try and find you need special tools and training to diagnose where the issue is in the system.

Hello, i could not find that exact model in our data. What i can tell you is you need to turn your multi meter to continuity mode, so when you put the two leads together they beep. Put on end on one side of the heater and one on the other. If it makes a sound you know the heater is not broken. and also do that one the defrost thermostat/Bi metal when it is in the freezer and nice and cold it should beep as well so you know that power can flow through it. if those test good you will need a new timer. hope this helps you out.

If you have no water to the ice maker or dispenser assembly I would look at the water saddle valve or water inlet valve. If the get plugged with lime and calcium deposits it will restrict water flow to both areas. See links below

The “PF” error code on this dishwasher stands for “power failure”. This error code will display if you shut off the power to the dishwasher, or if there was a power outage. You can normally just clear the code and run the dishwasher if there are not any other issues. It can also be caused by a bad electrical connection at the board or the main power connection coming into the unit. . Shut off the power to the dishwasher and check the electrical connections where the power comes into the dishwasher. I have provided a diagnostic guide link below.

Hi. I have attached a tech sheet on this unit for you. There is not an E0 error code, but there is one that looks similar to that for a thermistor error. Take a look at the tech sheet and find your error code. Follow the steps to find out what is causing that error for you.

Hi. First I would check for proper power to the unit. AT the outlet do you have 120V and a proper ground? How did this happen to the unit? Was there a power outage or something that caused this? If you have proper power I would have replaced the board as well for this issue. What part number did you install? The part number for the main control I found is p# DA92-00233D. Check for proper power going to the control board.

I have provided the technician sheet for your model. Do you have any error codes ? See service pointers on out of balance spin issues.

Hi. I do believe that if the dishwasher control recognizes and issue with diverter it will cancel or time out and store the error code. Get into the diagnostics and clear the error codes. Run the test cycle. This will tell if everything comes on and is working properly. I have not seen a faulty diverter before. It sounds like the shaft of the diverter that goes up into the sump may not be aligned correctly. I have seen this before. Did you pull the sump out and have to disconnect any connections? If so make sure all your connectors are good. Especially the motor connector.

Here is the parts breakdown to help you get this unit apart. Hope this helps

Where is this ice forming? Please try to be more specific than just “in the refrigerator”. Sounds more like air infiltrating the FF compartment from either a door not sealing properly or from a drain tube allowing air to be drawn into the unit. You really don’t want to start ordering parts based on what some tech line person told you, as he can’t see the problem either. Their advice has been sketchy sometimes, depending on who they spoke to.
Have the doors been left open for a period of time?
Frost likely to build if the door is left open for a long period of time. Make sure the door is closing completely and is not blocked by something between the door gasket and cabinet.
Are the doors opened frequently?

Frequent door openings can let in humid room air. Keeping door openings to a minimum will help, but may not completely eliminate frost or ice in the freezer. During months of high humidity (especially if a home is not air-conditioned), it is normal to see some frost and sweating on the interior walls or on food packages.
Are the air vents between the freezer and refrigerator blocked?
Ensure the air vents between the freezer and refrigerator compartments are not blocked. Objects blocking the vents will cause a decrease in proper air circulation which can cause temperature and moisture problems. Move any items that could be blocking the vents.
