Question about Intertherm Heating & Cooling
Inside unit will run all night the outside unit will run for 10 min and stop .it does this all night why
Some heat pumps have high and low pressure swiches installed to keep compressor from running when unsafe conditions occur that can damage the compressor. If the outside fan is not turing on, the unit is cycling on high pressure, if you see ice forming on the big refrigerant line coming from the air handler, then the compressor is shutting down on low pressure. Low pressure can be cause by lack of air flow through air handler or from a low refrigerant charge.

If your unit is blowing heat inside and it's not a heat pump. It will be most likely electric heat in your case.
Sounds like you have a split unit meaning the condenser is outside and the cooling and the heat features are inside or under your home.If your Rudd is a heat-pump the outside unit will cycle/blow cold air outside in winter and hot air will cycle/blow outside during the summer season. Now, if for some reason the heat is not coming on inside the house, would be the only reason that you would need to be concerned. Being a heat relay or breaker of could cause that problem. Hope this helps you, Sea Breeze

You may be right in looking at the motor. It uses a different speed on heat than cool. The heat cycle uses low speed, usually red. Some manufactures use blue (medium). Cool uses black, high speed. If you are confident, switch the low speed wire with the high speed and see if this changes anything. If the fan motor isn't the problem, check the other setting (cool) if the overload trips, you may need to look into a new capacitor or compressor, if so, you can install a hard start kit. these are start boosters, and are inexpensice, sometimes they will give another year out of the comp. but I've put them on and they have lasted 5 years.

colors can vary. you should be able to locate a wiring diagram inside the airhandler and out door unit. you will have to remove the panels. generally though Green is fan RED is power WHITE is reversing valve Blue is common YELLOW is the contactor (usually have to jump w and y terminals at robertshaw tstats. PLEASE DOUBLE CHECK AT SYSTEM DIAGRAMS!!

ok depending on what part of the world your in and the season . Winter: most split systems are designed around a set given temperature of operation , if this is a heating problem the what you are experiencing is the system going into deforest . bare in mind that those carrier splits are manufactured in china and are designed for about 35 deg C in summer and +5 in winter , anything out of this temp range will cause this , especially if it is running on freon 22 , in-which case it sounds like its short of gas to me . if its a new R410 a system , then check your filters and if they are clean and its still doing the same then it too is short , in each case a refrigeration mechanic is required.

Either the fan motor is going out OR the compressor may need a boost of power from a quick start.
When the compressor gets old, sometimes it requires a little extra power to get it going.
Your unit should be under work warranty if they installed it.
