A/C unit isn't working properly!

Greetings everyone! Slight issue that I need guidance with. Here are the stats:

Honeywell Thermostat TH8321R1001


Beckett CB201UL Pump

Indoor Unit: Amana ARUF303016BA

Outdoor Unit: Goodman G8Z130301AC

Home was purchased with system.
  • Contactor and Capacitor replaced less than a year ago.
  • Freon was added less than a year ago.
  • Batteries in thermostat have been changed.
  • Indoor Beckett pump isn't cycling water outdoor.
  • Outside unit fan isn't rotating but there is a light humming noise.
  • Indoor unit comes on. I hear a slight hissing noise when powered on, no one else can though.
  • Thermostat/System won't cut off when temperature is met. Have to manually power off.
We've powered the unit off from breaker, outside prong thingy (don't know the name), and the indoor unit for good measure.

I know nothing of voltage readings. The home is very far out, and many either don't want to service or aren't willing to be thorough enough to find the problem. I've had three companies come out since last week Thursday.

Please advise, if you can with information provided.

Thank you so much in advance!!

What will not power off when the temperature is met? The condenser? The blower?
3 different companies have looked and can’t figure it out?

Welcome to the forums.

Indoor Beckett pump isn't cycling water outdoor.


You know nothing of voltage readings but a meter is going to be needed to diagnose the system.
It is very hard to tell what's going on there.

roughneck77 The indoor unit and thermostat. Yes, three. Where the property is located isn't the best area for competent HVAC individuals, it seems. Everyone is just saying add freon, while also pushing a new system.

PJmax Not one company has brought out a meter. Is there a particular brand you recommend? I'm sure I can find one and let you all know the status.

I appreciate the responses everyone!

So the blower will not turn off. I’m not sure what you mean by the thermostat isn’t turning off.
Check for a call for blower at the low voltage terminal block. To see if it’s calling for the blower to run.

roughneck77 I'm not well versed in AC components... When the set temperature of 70 is reached, per thermostat, the system continues to run. I'm accustomed to it reaching set temp, and the entire unit will cut off. Is the system considered the blower?

The blower is in the air handler. For indoor air.

I'll got out on a limb here. Fan motor is dead, compressor runs until it overheats (hissing of refrigerant heard indoors) compressor overheats and shuts down. After it cools off, cycle repeats. It's actually never reaching the desired temp, just barely keeping it at set point, this is why the unit never shuts off. You're going to need a multi meter and know how to use it in order to troubleshoot correctly. Any HVAC tech should easily be able to diagnose what's wrong with you unit.
