Question about Heating & Cooling

1 Answer

I have a RUUD RCBA-3765G Coil. When my AC stopped cooling I went to the basement and opened the access panel. When I looked at the coil it was frozen completely, the insulation was frozen to the front of the coil and inside all the fins/tubing had about 1/4'' of ice. I defrosted it and the AC is working fine. My question is what caused this?? Thanks.

This could be caused by a low refrigerant charge or dirty filters restricting the airflow. Also it will happen if the indoor fan isn't running.

If you can't find the filters, maybe they were never installed. If that is the case you probably have a dirty/blocked coil.

What's wrong with your current AHU? Any Ruud dealer can assist you. Most 4 ton units work with r-22 or 410a. As a side note, most parts in an air handler can be replaced unless the case is rusted thru.

I have a ruud ac unit model # rcba 3765g. I removed the filter and look up at the coils and noticed that the dirt was caked on the them. What is the best way to clean them. It looks like it will take...

welcome to Fixya !

Here are some steps that you may follow.
Take come caustic soda ,(put a table spoon in one glass water) that will be in powder form (caustic soda) ,
if you do not have this caustic soda , then add shampoo to water (quantity same), take a small brush that should be a little big then a tooth brush manually dip the brush and clean it all the ways that the grills should be shinny.
As you have told us that from 5 years its not being cleaned so it needs a service , if you want to make it cool as you want this season then you have to clean it your self by brush ,and water+shampoo .or caustic soda. but it needs to be clean ,,if you can take it out the whole unit yourself and you have a a good pressure of the service stations have then you can clean it , but try to cover up wires or else you may have electric shocks after you clean and fit your unit so make sure to properly dry it ( with a blower or something ).

DO comment here if it helps you in any manner
Best Regards

It does cool the house but not as cool as normally does. Takes quite awhile to reach 70 degrees. Have turned off and back on again, turned off and washed outside box and has a new air filter in it also....

You can also buy some coil cleaner and clean the A coil. You can get coil cleaner from most hardware stores. The A coil on a split unit is inside the furnace look where the air conditioner copper lines go. there should be an access panel you can take off to get at the coil or you can access it thru the filter area. You will make a mess so have old towells ect... If its a combine unit where the blower is outside you can access it thru the side the air handler side of the unit. Usually you have to take the panel off on the opposite side of the unit from the external fan that is on top of the unit. When you find the A coil it will be obviouse it will be a radiator looking thing that usually is shaped in a A design. But if your unit can maintain 70 degrees now while its been around 100+ here it is doing a good job. Also look for leaks in duct work. good luck

My adp coil already failed in my only 2.5 yr. Old Carrier ac unit. I am now looking at an estimated $1500.00 repair. Coil is under warranty so the above cost reflects labor only. Adp serial #7107A07780....

Sorry, I don't have any solution but I'm in the process of replacing my 2 AC systems (4 tons by York). My RUUD dealer has provided RUUD ac and gas furnace with ADP coil and not using RUUD coil. Should I insist on using RUUD coil rather than ADP coil?

What would be wrong with a 99 caravan if the ac stopped working suddenly?

either the clutch on the pump went out or the system has no freon left.

My ac was working until we had a big dust storm and it stopped cooling

Wash out outsde coil first also check breaker. If coil is full of dirt it will cause high head pressure and overheating, Can trip breaker or shut down compressor.

The condenser coil is in the outdoor unit. Turn off the power. Take a garden hose without the nozzle. You want to use gentle pressure. Just simply using your thumb to control the spray. Spray the water up at an angle under the slanted lovers. use a generous amount of water. you should see the dirt coming our. You will have to take the cover off to clean that side of the coil. Be careful so you do not get the electrical controls wet when the door is off. The Evaporator coil is located in the supply air plenum downstream of the airflow. ( the top if its in a basement). You probably will need to open the ductwork.
Good luck.....
