Hi, when your unit starts to freeze-up on the indoor unit and on the suction copper line on the outdoor unit, this is due to a loss of freon. Because in your case, the air is not as cool as it should be or normally is. Some will ice up if the filter has not been changed on a regular basis, and the evaporator coil gets plugged with dirt. When it starts to ice over, you will loose 50% to 95% of your air flow. As long as you have good air flow, but not as cool with the ice ( you will loose some air flow if its been iced up for awhile ) you have a very small leak in the system and will need a recharge. They will normally leak at a place of least resistance like at the schradder valve where the freon is put in. If you have a older system, it may be in the evaporator coil. It depends on how much you have lost. You will need to call out a licensed tech to charge this unit. This is your problem indeed. Please keep me posted and informed on this. When you rate me, please be kind as I know you will. I thank you for this.
Sincerely,

Model mtb1950gr. Freezer stopped working. Fan is blowing cool air up there, but everything is completely thawed. Refridgerator part below it seems to be working fine. Vaccumed back.No change.


Your defrost may be stuck on. Cool air is not the same as freezing air. Frost free freezers use less than freezing air passed over and through the food to warm any ice crystals and move the moisture out of the freezere.

Ac unit is not cooling, the part on the inside keeps freezing up after it is frozen the air blowing is not cool. Sometimes there is a knocking sound from the compressor.


Freezing of the evaporator is caused by low air flow (fan problem or dirty filter),low refrigerant charge or leak. I would suspect a leak (noisy compressor) because the compressor lubricants are in the refrigerant.

Ac unit isn't blowing


It sounds like your freezing up at the coil, which in turn, blocks airflow across coil and only a small amount of air comes out of the vents. This also explains the cold air coming from fan on the outside unit, since the system cannot absorb the heat from the inside of the house through the coil. Your air outside is usually blowing out warm to hot air because thats the heat it rejects out of your system. I would turn the thermostat to "OFF" and turn just the fan setting to "ON" instead of Auto, this thaws the system out faster. Give it time to fully thaw, make sure filters are clean, and check airflow. If airflow is back to normal, your problem is more than likely the charge of refrigerant. If you have to call a technician out, make sure the unit is not frozen at all before they get there, they would not be able to do anything with the system froze. Hope this helps and good luck!

Sounds like the contactor in the condensing unit is stuck. That is why it will not turn off when the thermostat is satisfied. If the inside air handler is not blowing and the outside condensing unit is running, then this will cause the inside coils to freeze up rather quickly.
The contactor is located in the outside condensing uni in the electrical compartment.
If it is sticking it will need to be replaced.

Coleman deluxe blend air ll it starts up


The blowing fan is not rotating at the rated speed. Check the fan capacitor and replace.

Check motor also if the capacitor is not at fault.

Left door open, closed next day, but only blowing cool air now


You will need to turn the unit off and let it completely unthaw. There is frost that builds up in the ducts and behind the panels when the door is left open that will cause the unit to not cool or circulate where needed.

Heater is blowing luke warm air. does not get any hotter


Quite a few idea's come to mind.
1) Thermostat is stuck open, causing the engine to run cool.
2) The vacuum valve that opens and closes the air "flap" is stuck open, allowing cool air in all the time.
3) The vacuum valve that opens and closes the line that feeds the heater core isn't opening all the way.

Air not blowing out forcefully


If you had a company out to do this, it sounds like they didn't check things very well. It is very possible that you have a leak that needs to be repaired. Also, it could be a problem with the indoor fan or a plugged air filter. The coil is probably freezing over with ice because it is too cold caused by one of these problems
