I would start by washing the condenser coil thuroughly, then if it continues check refrigerant charge.

A copper thin tube from the unit is very hot. Is it normal?


Yes, well somewhat normal. The refrigerant leaves the compressor at high temperature and flows through the condenser coil where it cools about 20 degrees warmer than the outside air flowing through the condenser. Many small air conditioner units use a small copper tube (capillary tube) of a specific diameter and length for that system to cause a decrease in refrigerant pressure between the condenser and the evaporator. The refrigerant leaves the compressor as a gas at high pressure, cools in the condenser and changes into a liquid. The liquid flows through the cap tube and cools more as the pressure decreases and gets closer to the evaporator. The refrigerant boils and evaporates under the low pressure of the evaporator and turns back into a gas. That gas is pulled back to the compressor.
If the condenser is not cooling the refrigerant enough, the tube can become extra hot. Efficiency is reduced. Actual temperatures throughout the system depend on the type refrigerant used, suction and discharge pressure at the compressor, outside and inside temperature. Tables, charts and graphs for various pressure-temperature relationships can be found in refrigeration books and chemical web sites.

Why does the compressor on my goodman package unit turn on and off before completing a cycle?


There is several possible causes. The most probable cause is wrong charge. Many units have a low suction safety on the low pressure side of the compressor. There is often a high pressure swithch to guard against over pressure also on the high pressure side. If your unit has the condensing fan stop in mid cycle, the compressor has inherent motor contacts inside the compressor to help guard the compressor from overheating. I just recently had to replace several customers main contactor because the contactor contacts were severly burned and sometimes could pass current and sometimes could not. I also had a few customers whose condensing unit was so dirty that the compressor was overheating causing the inherent motor contacts to open. Hope this gives you some ideas to look.

My goodman unit (1994) makes the loud noise, like a buzzing noise. The unit works, the blower blows air into the house, the air is cold, but the outside fan that blows across the condenser piping isn'


you need to replace your condensing fan motor. the noise you are hearing is the compressor working against a lot of pressure because the heat is building up in you condensing unit. Prolonged operation without an operating condensing fan motor will cause your compressor to burn up, and then you will have the cost of a compressor changeout to the cost of a condensing fan motor.

My Sanyo ac outdoor is overheating and then goes off what could be the problem


If the unit is overheating, I'm assuming the compressor is getting hot. It could be drawing high amps, do to a bad capacitor, bad motor, a dirty condenser coil. It also could be low on refrigerant and not getting the proper cooling back to cool the compressor.

Goodman heatpump fan runs, condenser wont start


Either the condenser fan has bad bearings, or it has a defective fan capacitor.
Turn off the breaker to the outside unit.
Spin the fan blade by hand.
If the fan blade spins easily and will spin a few revolutions with no problem the fan bearings are good.
If not, replace the fan motor due to bad bearings.
I am pretty sure you fan motor is bad because with a bad capacitor the fan motor will not get up to speed and may just sit and overheat.
I'm leaning toward a bad fan motor.

High amps in compressor


Hello, if the unit is overcharged, dirty condenser or non condensables in the system all will cause the compressor to run at higher amps. Try cleaning the coil first and see if it helps, if not gauges must be attached to the unit to check where the pressures are on the system.

The compressor suddenly trip off and it runs and after few minutes it trip off again


Compressor tipping is typically due to overheating. A single bimetal disc thermostat (e.g. Klixon brand device) in located within the motor windings within hermetically sealed compressors which will cut off motor current after the local windings have sufficiently overheated.

Unfortunately, by the time this limiter has activated, the compressor motor and pump has typically already suffered mild to major damage.

Compressor overheating is typically a result of low freon. The freon, besides cooling the compressor, also carries the lubricant, so low freon results in a hot compressor with poor lubrication, with some degree of permanent damage by the time the internal limiter has activated.

There are a few other possibilities, depending on system design, but some version of the above scenario is typical.

When the compressor runs hot, this also initiates chemical changes in the freon and oil resulting in acids with further attack both the compressor pump, motor windings and motor bearings, a viscous circle.

Compressor overheating can also be a result of contaminants circulating within the freon or evolving mechanical failure problems within the compressor pump or motor.

Better systems (very few high end residential central AC systems) include OEM or field installed high freon pressure and low freon pressure cut out switches connected to circuits which stop the compressor and keep it off when pressure are well beyond desired.
These are far more effective in protecting the compressor and preventing permanent damage.

Additional protection options are a compressor discharge temperature limit switch (shuts off the compressor if the outlet freon goes well above desirable outlet temps), and a flow switch which sense adequate condenser fan air flow and only allows the compressor to run when adequate air flow is present (a second or so after the condenser fan has started). (Since condenser air flow is what removes all the system and interior heat, the compressor should not run unless airflow is appropriate.)

While all the above 4 safety device strategies are relatively inexpensive, they are not present in the vast majority of residential AC systems sold in the US.

Fan motor will not come on


That thing connected to the capacitor is a booster for the compressor .But if the outside fan doesn't work , the compressor will shutt off on overload because the high pressure in the condenser coil.
First try to replace the capacitor in the condensing unit (it's the only one that works for the compressor and the fan motor) ,but if the fan doesn't start, you need to replace the fan motor.

I live in south texas overnight the ac stopped GOODMAN MODEL


Is the condenser fan (outside) turning? You mention that it's hot but don't say if it's turning or not.

These fan motors normally run pretty hot, but not so much that they shut down due to internal thermal overload protectors.

Both the compressor and the fan have termperature overload protectors to keep them from burning out the motor in the event of an overheated condition. The condenser fan must be running or high freon pressure will put an excessive load on the compressor and it will 'kick out' the high-temp overload protector.

Turn off the unit by pulling the outside disconnect (in a small box near the outside compressor unit) or flip the AC breakers in the breaker box. Wait about 30 minutes for the unit to cool off and turn it back on. If the compressor and fan both run for awhile then kick back off, or the fan motor seems to be working under excessive strain, you've probably got a bad motor start condenser (inside the unit) that little round can that is connected through the fan motor wiring. If it's swollen or leaking, it's almost surely defective and even if it's not, excessive load on the motor is a classic sign of a bad start condenser.

You can usually find these at electrical supply stores, well-stocked hardware stores, or most certainly at an HVAC parts house. Be sure to replace the old one with one of the EXACT same value (in voltage and Microfarads (mF) capacity. The shape may be a little different, but as long as the electrical characteristics are the same and is rated at the same or higher voltage than the original, it will work.

Connect the new condenser, mount it to the frame, and restart the unit. This should take care of the problem.

Hope this helps.

Squeeling noise coming from AC, compressor is on, fan not turning


The squealing noise is coming from the compressor. This noise is common when the unit reaches extreamly high pressures. The pressure is most likely high because the fan is not running. Since you can spin the motor it could be that the motor has damaged windings. Leave the unit off until the repairs are made to ensure no further damage to the compressor. You will need a multi meter and some experience reading wiring diagrams to properly diagnose the system. You can perform an amp draw on the motor to see if it is in spec. You can measure the volts to the motor and see if they are in spec. Finally the contactor can be measured with the proper meter to see if it is working properly.

My suggestion is to have the Motor and capacitor both replaced. Also inspect the wiring in the condenser electrical compartment for any signs of damage or burning.
