Question about Maytag M3V12S2A Air Conditioner

1 Answer

My air conditioner no longer blows out cool air. I can hear the compressor come on when I lower the thermostat. I had it cleaned in the fall so it is not a dirty filter. Can I recharge this myself?

There may not be a service port for adding the refrigerant. The only kind you can buy without EPA CFC certification is R134a so unless it uses that type you won't be able to buy it. You will have to take the cover off to see if it has a service port. You may want to price getting the refrigerant charged then price a new unit and see which is cheaper.

The ac starts to blow cool air then it starts to blow warm air. and this continues on and off and on and off. what is the problem and why would it do that


Hello, the thermostat on your ac senses the temperatur of the evaporator coil, this is what turns the compressor on and off. It is normal for the compressor to turn of and on every hour or so, however if it keeps doing it too often then either your thermostat should be set lower or the thermostat is defective and must be replaced.

My air conditioner is not blowing cold air. What can be done ?


look for a couple of things ... if the compressor just buzzes intermittantly but doesnt run then suspect its starting capacitor (small rounded metalic rectangle) .. that has wires connecting it to the compressor .. .. if you can hear the compressor start but it still doesnt cool then you likely need refrigerant added .. thats done by adding a saddle valve service port ... any leaks have to be repaired ..

How do i figure out why it's blowing cool but not cold


It sounds like the compressor is not coming on. It may be the thermostat. Take the metal wire with the fat end, make sure not to kink the wire, this is the sensing bulb Warm it in your hand. If you hear a click it works and you need a new window unit. They cost as much to get fixed as a new one. If the thermostat does not click then that is the problem.

Air compreser not turning on. fans are blowing but when you turn to cool the a/c wont engage.


Either a problem with thermostat, or perhaps faulty start relay for compressor. Do you hear a "click" or a slight "hum" or both when switch to cool?

Air conditioner doesn't blow cold air. Continues


If the a/c fails to continue to blow cold there could be a few problems you can look for. First once you activate the system check to see if the compressor kicks in. You will hear the compressor humming . Once the a/c quits cooling go and see if the compressor is still running. If its not running its probibly gone into thermal overload (compressor overheated). If that is the case then you need to check to see if the coils are icing up if they are icing up then the problem is with 1) air flow restriction filter dirty, coils dirty simple repairs there replace filter, clean evaporator coil with a coil cleaner that can be purchased at a home repair store cleaning the condensor coil the same. 2) system is low on freon in which case the system will need to be recharged. Also, If you have a digital thermostat replace the batteries that may also be of some help. Good Luck on repairs

You have either a faulty thermostat, dirty condenser and evaporator or a faulty run capacitor. Need to service soon before the compressor is damaged. Sea Breeze

I bought a haier electronic control air conditioner model HWR10XC6 on 6/30/08. I installed it. When I try to use the cool mode the air conditioner will only blow out cold air for about 5 - 10 minutes and...


Hi,
It sounds as if the compressor (that provides the cooling) is cutting out due to either a faulty thermostat or is itself overheating.

Obviously check the thermostat is able to move between it's minimum and maximum levels, anthat this corresponds to the compressor cutting in and out.

With maximum cooling selected, the compressor should not cut out untill the thermostat says it's cool enough. If it does, there is a fault, and you have every right to a refund or a free repair/ replacement.

The fault is usually centered around the compressor electrical components if it is not under any warranty, but it should be. Even if the store does not want to know, the manufacturer should back it for 1 year.

Thanks for using Fixya!
If you need to attempt repair - ask again.

Thermostat ?


The Air conditioner are good only the adjustment of thermostat are the problem, select the thermostat in lower #3 you observe the thermostat will off in such time temperature reach to #3 If you full adjustment the compressor will not off.
In fan selector the compressor will autamatic off because no connection attached fan only .
