Ckl36-1d freon lines and a-coil covered in ice. no air is able to get past frozen a-coil

The most common cause of coils, lines or components freezing over are low refrigerant charge, lack of airflow across coil or a blockage of the condensate drain. If the outdoor coil is frozen over then the defrost mechanism may not be working properly.

Do you see any ice build up on the back wall of the freezer compartment? You probably have one of the following problems: A failed defrost system, meaning the defrost timer and/or element has gone out and your evaporator coil is frozen over; you are low on freon and this too will cause your evap coil to freeze over until the freon drops so low all cooling stops; or there could be a clog in the capillary tube which is the very small diamiter copper tube that carries the condensed liquid freon to the evap coil. Unless you have gauges, a licence to buy freon and service valves (or a buddy with such) you are limited to what you can do. Here is my advice:1. unplug the frig and let it defrose over night, unplug the frig and empty the freezer to remove the back cover to look for ice, a frozen fan and if so get your hair dryer out and melt the ice so you can test the fan and the defrost element (you will need a volt/ohm meter to do the element check. You can do it.

Ice cream will get hard when the temperature is closer to - 20 C or -1 F scale. Water becomes Ice at 0 C or 32 F scale.

Ice cream soft means your freezer is not cooling enough.

You were cleaning the coils? Both condenser and evaporator coils? Cleaning coils and then loosing cooling in the fridge is not a good sign or combination. May be there is a freon leak and the seal system is low on freon now.

Call a service tech to check the seal system.

Unfortunately, if it is a leak you may eventually buy a new fridge after spending money on freon fill up, freon system sealant, leak check etc etc... No good news. Sorry

Hi, there are a couple of things that will cause your air handler to ice up, some you may be able to take care of your self, and the last you will need to call out a service tech. First of all, you must have a clean filter at all times. 2nd, if the indoor coil has gotten dirty, this will cause decreased air flow across this coil and it will ice up very bad. Cleaning or I should say, getting to this coil to clean can be a job. You will have to bend the sheet metal panels, remove some screws, and work around the freon lines to get back to it enough to remove the sheet of dirt that is covering the coil. It will peel off like a sheet. When they get this way over the years, they will block the return air back through the coil, and it will ice up.Once it is cleaned, you may have to buy a roll of aluminum tape to seal the areas that didn't go back together very good. If your blower motor is not moving air very good, like it is ready to go out, moving slow, or making noise, this will do the same. The last thing that will cause this, is the unit has a small freon leak. If your air handler is gas, you can turn on the heat to melt the ice off faster, if not, turn just the fan on to melt the ice away. Once its gone and you have good air flow, turn the a/c back on and go to the outdoor unit. Place your hand above the fan guard to see if the air is good and warm to hot. Find the large copper line below and grab hold to make sure it is good and cold and is starting to condensate. The smaller line, discharge should be good and warm to hot. This will tell you the freon level is real close to being full, so your problem will more then likely be a dirty, plugged indoor coil. More then likely, this is your problem and would be something you could do your self to save you $$$$. I hope I have helped you on this and given you some direction to go on. I have done this for many years, and know the signs very well. Please don't forget to rate me as I know you will be kind. Please keep me posted on the outcome.

Normally when the suction line freezes which is the larger of the 2 lines, #1, its low on freon again and unit has a leak. They are sealed systems and they should never need freon only if they develop a leak. So, this we know. Also, if the air filter is dirty and plugged, and the evaporator coil at the air handler is dirty will cause icing of lines and coil.Not enough air flow across the coil due to a dirty filter. When you set your thermostat to go below 76 degrees, the unit will work harder to keep up to bring the temperature down and if you have a leak which you do, the suction line will ice up. A Ruud 060 is a 5 ton btu unit, good size. Who ever added freon should have done a leak check on it. I would recommend you calling them out as it is low again and do a complete leak check, add dye to the system or there are many ways to do this. If the leak is not found it will continue to ice up. By E.P.A. standards, they cant keep adding freon, they must find the leak.This is all about you can do, is check and make sure you have a return air filter and its clean, and if it continues to ice, have them find the leak, repair it, and re-charge it. I wish you the best.

If the indoor coil is icing up, you are either low on freon, or the indoor coil is very dirty. This will cause it to ice even though you have replaced the filter. See if the suction line/large copper line has ice on it on the outdoor unit. If so, its low on charge or the indoor coil has plugged up and not getting enough air flow across it. Please keep me posted.

The lines that are frozen are not ones you can run bleach through. The best way to troubleshoot this one is to first turn off the unit and put it fan only mode to thaw and de-ice the coils. Then check the air filter to be sure that it's clean and that there's nothing blocking the air flow. If the filter is clean then you should check the coils just beyond the filter. Check to be sure that the coils are clean and free of dust and debris. If the coils are clean then you may be low on freon. At this point it does require a certified A/C technician to leak test and charge the system. These are the problems that would cause your unit to freeze up. Hope this helps, good luck!

first you need to determine if the furnace coil is frozen or iced up. The water around the furnace means that the water is not draining where you want it to go. This can be from a blocked drain line or a frozen coil. The fact that the system is not cooling may mean that the coil is blocked. Turn on your blower only and let the air flow warm the coil if it is frozen it will start to melt. The system is then low on charge or the air flow is blocked by a filter or bad blower

if cover is off there will be no air down there..was there frost on the coils ? if no then compressor is not running..if compressor is running and no frost..no freon or compressor valves shot.

frozen coils not always means freon problem. low air flow across evaporator coils could cause freeze up. if door is opened and closed an abnormal amount could cause a freeze up or even something pushed up against the air intake in the refridgerator. i would thaw it out completely and restart it, theres a chance it was nothing major. good luck
