Question

I just moved into a house with a honeywell air conditioner - Model #AR42-1, Serial #0112447735. I have a few questions. The air temp is set at 76 degrees and it is running, but the temp on the display shows 86 degrees. The room that has the display panel faces West and I have no screens on the windows (windows are about 3/4 of the wall space). Is it just to hot outside to get cool inside? There is a switch connected to the air conditioning unit (looks like a light switch) that is in the off position (down), what is this switch for? Can I get a copy of the owners manual for this unit?

Any assistance you can provide would be wonderful. Thank you !!!!

Hello,

 

The ac unit is made by Goodman. The thermostat is most likely a Honeywell.

 

First of all, you have a blower unit inside and an ac unit sitting outside. Is the outside unit running?

The unit outside is making noise and the fan on top is moving.

It sounds like maybe water running through the unit, but I do not think I hear any air blowing.

Ok, there are 2 pipes that run from the outdoor unit to te unit inside. One of thos pipes has black insulation on it. Feel that pipe right as it enters the indoor unit and tell me if it is hot, cold, frozen etc?

I can't reach the very top, but about a foot down the black insulation feeling room temp to cool.

I am sorry, I need you to feel the copper pipe under the insulation. You can do this outside also.

I just noticed it about an hour ago and now the temp is at 89 degrees. I did also notice on Sunday in the afternoon it got in the 80's and cool down about 7:00 pm.

Ok....curiousity now about the "switch" . You say it is connected to the ac unit...flip that switch and tell me if something turns on or turns off.....

I flipped the switch up and nothing happened. I then flipped the switch back down and the whole unit shutdown and so did the outside unit. I can not get the unit to come back on. I tried flipping the switch up and down again, but nothing is happening.

You will need to set the thermostat again and it most likely has a 5 minute delay before it will kick on.

 

Now....have you checked the air filter yet?

Okay, the unit is running again. The air filter looks pretty dirty. Can a dirty air filter cause it to get this warm in the house? I took the air filter out.

Accepted Answer

Yes ...poor airflow is the number 1 reason for air conditioning issues.

 

I recommend you get a new air filter...set for 76....and then see if it responds better. I am avilable for follow up.

There is the manual link again for your outdoor unit.

 

Let me know if you need further assistance.

how come I still don't feel any air blowing?

Posted by Billy 192 days and 1 hours ago.

Info Request

The filter was plugged so the unit is most likely frozen over.

 

Do this for 45 minutes as a test and I think you will see a big difference....

 

turn thermostat to "off"......and Fan switch to "on".....wait 45 minutes. This should thaw the coil that I believe is frozen up. Try that and then set back to "cool" and get back with me.

It looks like that worked. It has cooled down 6 degrees in a half-hour. Thank you so very much for all your time and help. I am sure you saved me a load of money. I am currently unemployed due to work force reduction. Money is tight. You are a life saver.
