HotPoint No-Frost Side-by-Side refrigerator CSH22GR. Freezer is cold enough (and not iced up) but refrigerator will not get below 48 degrees. We have cleaned all the dust and cat fur from the coils. What else should we try?

chances are you have a faulty module (board) sounds like you'll have to call an engineer oput to replace it

SOURCE: cooler wont cool below 48 degrees.

Keep a thermometer handy. (adjust temperature control knob accordingly)
Periodically monitor temperatures inside your cooler. (adjust as necessary)
Keep the refrigerator door closed as much as possible to avoid temperature fluctuations

The temperature of the refrigerator compartment is
controlled by adjusting/setting the thermostat control
knob, located on the ceiling of the refrigerator
cabinet.
To start the refrigerator, and achieve maximum
cooling quickly;
• Turn the temperature control knob (using a coin
or screwdriver) clockwise to the furthest
(maximum) setting on the darker blue section of
the graduated control dial.
• Allow the refrigerator to run at this setting for 3~4
hours.
• When maximum cooling is achieved, turn back
the temperature control knob setting to the 2:00
o'clock position on the graduated blue control
dial.
• Correct cooling temperature is a key factor to
consider in storing and dispensing draught beer.
• Optimum temperature for serving draught beer is
between 34ºF ~ 38ºF.(1ºC ~ 3ºC)
• To maintain temperatures ranging between
34ºF ~ 38ºF.(1ºC ~ 3ºC) We recommend the
thermostat knob be positioned at the "2:00
o'clock" setting on the graduated blue control dial.
• To turn off the refrigerator, (no cooling) rotate the
control knob to the "0" position.

if you have frost in the freezer it either has an air leak on the gasket or the defrost system has failed and you need to call an honest appliance repair person,don't call sears$$$$$$$$$,check all around the gasket first,mike

SOURCE: the temperature won't go down below 48 degrees

Maybe be defrost problem. If there is ice build up in back of freezer then its not defrosting and blocking air flow. also made sure fan is working on inside and outside coils. May need to call in a tech if any of the 3 problems are present. can also be freon, compressor or control problem.

SOURCE: Freezer frost then loss of cooling

There is a block of ice that is causing the air to not flow across the coils as it should. This is why the temp has risen. You can do a manual defrost by un-plugging the unit over night but I would call out a ref tech to check the defrost timer and the freon level. Hope this helps. Good luck. Please re-post with updates.
