Blowing warm air,not colling - Mitsubishi MS17TN Air Conditioner

Any Freezer does not stay at any one temp. If you freezer is part of your refrigerator then it goes through defrost and the temp will rise. When the compressor comes back on it will drop. How much food you have in your freezer will also be a factor. Not much food and the unit will flex widely in temp. too much food and the fan can not blow the coll air around properly and msy cause it to warm up. If you need more help please add additional information being very specific.

There is normally more that one fan. I would first blow it out with air. Normally a colling pad helps. Use canned air to blow out the dust balls.

the one thing that comes too mind is trapped air-when i do a radiator I always start up and warm engine so thermostat cycles a few times to make sure that you dont trap air in colling system. you did not say so but if you didnt, its really not a bad idea to change thermostat and gasket when digging into colling system. they are usaully fairly cheap.

Change thermostat to heat mode. May be you're keeping in cool mode.

Hi,

Many times a freezer and/or refrigerator do not work right because of a dirty condenser coil...there are also many other things that can go wrong.

If you are hearing a clicking or buzzing then check out the last two tips.

If your refrigerator is running but warm, then...

Check out these tips that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Refrigerator or Freezer not Cooling or Getting Cold

Sounds like you need a blower motor resistor located down under dash on pass side next to blower motor. This is a comon problem and I have changed many of them. thats just the fan speed problem. Ive seen the blend doors break easily on those jeeps. thats inside the heaer core box and moves the flap from hot air to cold air. If it is stuck halfway -or mostly to cold- you may only get luke warm air. If they had the heater core out-maybe they possibly broke it.

if your sayin the unit isnt cooling then you need to see if it blows any air at all if so and its just warm or regular air then fist check your run capacitor to see if thats bad and at the same time put your hand on the top of compressor to see if thats running it should feel like a humm if not running copressor is probably bad if it is running then most likely its low on freon and if thats the case you have a freon leak some where in system and the new freon laws these days are requiring the a/c company to find and fix leak before adding freon .some companies will just fill it and the same problem will accur soon again.send back more info ,like is unit blowin air is compressor running and i can pinpoint problem easier thanks and let me know the outcome

Have your AC "charged" with refrigerant

i need to know how is not cooling the car?
is the fan blowing air or is the blowing air not cold?
it probably isnt cold.lets try that.
put a set of 134a ac gauges on the system and verify pressures.if it has low freon you may hear the compressor turning on and off.if so for sure its low and you will just need to add freon.
go get a 134a fron fill kit not the conversion kit.
and begin to fill untill the comp stays on and air is blowing cold.then stop filling and enjoy.
do not over fill as this will cause it to not cool again.

first thing you need to do is replace the fuse then dissconnect the positive wire from your fan. now warm upp the bike till the fan should turn on .
now if the fuse blows we need to find the short if it doesnt blow you need a new fan.
good luck
