Re: goodman heat pump trips sometimes no know cause.
20 AMP Circuit, huh? More on this below.
The tech probably didn't put a hard start kit on, but if he did, I hope he added the resistor to the start capacitor, or you could have a problem in the future. He probably put a soft start on it, a 2 wire device which looks like a capacitor. But only you will know for sure (or he.). As for warranty, manufacturers don't care about soft or hard start kits. In fact, they like 'em, because they extend the life of the compressor, which keeps them from having to pay for a new one.
I would be concerned with a 20 AMP circuit for anything higher than 2 tons. Take a look at the nameplate rating on the side of the condensor and tell me how many Running Load Amps (RLA) this unit is supposed to pull. Also need to know your line voltage at the condensor, with the unit running.

Re: goodman heat pump trips sometimes no know cause.
Short cycling of the compressor can be an inconsistent cause of a breaker overload. It happens when the compressor start winding is "jolted" into operation several times over a short period this can happen when there is a loose power or control wire connection that is broken from the vibration at start up of the compressor or by the occasional "jiggling" of the mercury in older analog thermostats. I suggest that all electrical connections are checked and that you use a newer model thermostat, if its not already that has a built in start delay circuit.

Without looking up the specifications for this heat pump, I cannot be certain, but I expect the operation to provide cooling may require more power than when heating. You probably can find the specifications online for this unit. As you probably know, power is measured in watts and is calculated by voltage times current. This also is likely to be 240 volts operation. If you take the specified power on cooling and divide by voltage (240), that will indicate the current in amperage that will be required to start it. Your circuit breaker is set for current and needs to be a higher current than is required. If that is the problem, you can buy circuit breakers at Home Depot or Lowes. You have to remove the front panel of your breaker box and snap out the circuit breaker. To be safe it would be good to turn off the main breaker switch before you open the front panel and remove the circuit breaker for the heat pump. Should your calculation of current required be less than the rating of the circuit breaker, that implies a malfunction of the heat pump in the cooling mode and would require a service call to the local representative of the heat pump manufacturer.
very likely a defective compressor. while there are other things that could cause the tripping, 90% of time it will be the compressor. generally, it will not be cost effective to repair the system if it is.
DO NOT install a 20 amp breaker, you can cause a fire. The breaker is rated for the WIRES, and unless you change out the wires, the 15 amp wires will overheat and can cause a fire.
Typically, A/C units need dedicated power, with nothing else on that circuit.
One step that you may try is a new 15 amp breaker. Once a breaker starts tripping, is starts tripping earlier....
You may wind up running a new circuit for the A/C, if you do, size it for the A/C.
Check the breakers on the unit How many KW--electric heat? Check to see if you have the right wires wired up to the correct breaker cause some units have 40---and ---60 ---amps breakers and your thickest wire could be wired to the 40-amp breakers,, (some 5 KW pullls 19-23 amps respectably some breakers have 7.5 KW heat stips and pulls more and if the wire size can,t cary the amps, then all you have to do is reduce a heat strip.
Hi, When a breaker starts to trip on any appliance, it is drawing more amps then the unit is rated for. It should have a double pole 30 amp breaker if it is a 240 volt dryer.The first thing I would check would be the breaker and the 2 hot wires feeding it. Over the years, the wiring sometimes loosens up due to heat and they may be loose and just need to be tightened up. If you turn the breaker off, it kills the voltage to the wires going into it and you can then tighten them. If you are not comfortable doing this, maybe you know someone that can help you out.Also, overloading the dryer with a lot of cloths will cause the breaker to trip. I am sure that after 2 or more years that you are aware of this, just another cause.You may also have a problem in the motor, which draw a lot of amps if it over heats.You may have a lot of lint build-up around the motor and heating elements that should be cleaned out by removing the back of the dryer. Be sure the power is off before though. Try running the dryer with no cloths in it to see if the breaker still trips.If it still trips, I would say you are loosing the motor, but would check the breaker anyway. Please let me know what you find. Sincerely, shastalaker7
GFI devices are prone to degrade over time. Also, when used outdoors there are additional moisture issues that may cause sufficient current leakage to trip the breaker.
I had a similar problem this Spring. I was using a 20 amp GFI "master" outlet that protected two additional outlets 'downstream' of it (wired to the 'load' terminals on the GFI outlet- I'd have the check the doc. to see what terminology was used here). The pump was plugged into one of the downstream outlets.
Replacing the GFI seemed to solve the problem. I did ante up $20 for an 'outdoor' model of the 20 amp GFI unit, several bucks more than the standard 'indoor' unit - have no ideal if that represented additional value or not.
Note also, that this is the third such pump I have used for my pool cover. The other two failed to come on at all after about a year's use. The mfg replaced them under warranty (I may have had to send back the old pump - I forget!).
