No not normal, this is a sign that the unit has been overcharged with refrigerant. If it is just frost or condensate on the copper pipe that is not a big problem. But if the frost extends onto the compressor dome, then I would be worried. Sometimes fridges are charged in an area with a lower ambient temperature and then moved and sold in another area, hence the slight overcharge. No problem. Hope this answers your question. And yes when the unit cycles the frost will melt and of course drip onto your floor.

Not cooling


Cut everything off for a few minutes then turn it back on and listen for a click from the compressor relay as the compressor tries to start.
Is the compressor motor running.If no check starter/overload relay. The relay is a small usually black cube shaped electrical part plugged into the compressor or wired to it nearby. It may appear burnt or rattle when shaken if it's bad. The two connections should show continuity with an amp meter. If it's good then it's most likely the compressor causing the problem.
Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm




Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).
If it's iced up really heavy you have an auto defrost problem. Melt the ice with a hairdryer and check the defrost system.

Freezer compressor running constantly


Below the evaporator fan behind the back cover inside the freezer is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

If it's heavy buildup-
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

The freezer fan works, the compressor hums but the fridge does not get cold, nor does the freezer. Even with the settings on max.


Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

AMANA ARSE66MBW SIDE BY SIDE FREEZER COIL FINS GET TOO FROSTED ?


The frost should be uniform on the coils. Uneven frost pattern is a sign of low freon. Most systems are sealed but a qualified tech can recharge the system after finding the leak and cap it off.

your on the right track with the frost issue. but make sure your fan is running at the evaporator durning normal compressor run time. if there is not alot of frost build up at the evaporator the only other thing it could be is low on freon
