My upmc-030jaz runs continuously, it will be warm air for 20 mins then cold air for 2 hours, thermostat stays at the same temperature....or even declines a few degrees, but when reaches desired temp it will not shut off...techs have been here 5 times and keep replacing compressors...getting rather expensive....HELP! =(

There are plenty of reasons this could happen like the following: PROBLEM POSSIBLE CAUSE Loud operating sound level • See "Sound Information" section for explanation of normal operating sounds Freezer too warm. Compressor not operating • Freezer temperature set too warm • Defective compressor • Defective overload or relay Refrigerator too cold • Refrigerator temperature set too cold • Chefs Pantry control set too cold or misaligned allowing freezer air to escape into refrigerator section • Freezer temperature set too cold • Restricted condenser air • Refrigerant shortage or restriction • Refrigerant overcharge Freezer too warm. Compressor cuts off on overload • Heavy usage • High ambient • Restricted condenser air • Defective condenser fan motor • Loose or missing condenser fan blade • Improper voltage • Defective relay or overload • Compressor motor winding • Non-condensibles in system • Refrigerant overcharge Freezer too warm. Compressor operating • Freezer temperature set too warm • Restricted condenser air • Defective condenser fan motor • Opened door • Heavy usage • Defective freezer fan motor • Opened defrost thermostat • Opened defrost heater • Loose or missing freezer or condenser fan blade • Heavily frosted evaporator • Refrigerant shortage or restriction • Inefficient compressor Refrigerator too warm • Refrigerator temperature set too warm • Freezer temperature set too warm • Return air or air supply duct blocked • Chefs Pantry control set too warm or air supply tube blocked • Heavy usage • High ambient Problem Possible Cause Freezer too cold • Freezer temperature set too cold Long off cyde • Low ambient • Freezer temperature set too warm Short off cycle • Heavy usage • High ambient • Freezer temperature set too cold • Light constantly on • Poor door gasket seal Long or continuous run cyde • Heavy usage • High ambient • Inadequate condenser air flow • Freezer temperature set too cold • Loss or restricted refrigerant Short run cycle • Light usage • Low ambient • Freezer temperature set too warm Exterior cabinet condensation • High humidity. Design accepts beads of water on cabinet exterior after 4 hours with 0° to 2°F (-18° to -17°C) freezer food temperature and 38° to 40°F (3° to 4°C) refrigerator food temperature in 84% R.H. conditions. See "Typical Sweat Pattern" section under above conditions. • Freezer temperature set too cold • Poor door gasket seal • Insulation void

there are 3 things to be considered,first,if the compressor motor `s connectors are having loose,it gives a hi ampere to your RELAY that can cause to its contacts being fried,second,the compressor motor itself is gaining a hi ampere already i.e. having unusual sound that can cause heavy friction inside the turning mechanism and third the last but not the least,maybe this time,the tubes or the compressor itself having very small holes that causes to the refrigerant to escape and it doesn`t gives off cold air.

Hello anonymous freezing girl.

The one thing that will do precisely what you describe is a
FAILING (or absent) thermostat...

Typically located at the engine end of your to
RADIATOR HOSE... b'twix $10 & $20 USD...

For MOST all engines to run efficiently... they must
reach & maintain an operating temperature of 180 °F
(Fahrenheit)... Temperatures vary by engine size...

I am here daily...
merely comment me back: happy to discuss

Sounds like fan & limit control
If temp on limit reaches max temp what happens gas valve deenergized,as MTR continues to run begins to lower temp. Thus reenergizing valve
Check filters,MTR speed for heating

seer is dependent on what air-handler and coil it is mated with.

mine does the same

As long as the temperature is staying where the thermostat is set I would let it cycle through as it is doing.

Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.

yes I would switch it over due to the fact that the balance point reached. Since I'm not there to look at the system monitor the actual temperature inside and if you cannot maintain the setpoint on the thermostat you may have to bring it back on. I've seen recently that there was not enough backup heat to keep the house warm enough during cold spells. Stay warm.

If the room is at the set temperature even when the rad are warm the boiler is doing its job. It takes steel rads up to an hour to cool down so if they stay warm to the touch that is normal.It takes steel rads a long time to heat up when they get cold so its cheaper to let them not get real cold.I was told not to put a programmable thermostat on our boiler simply because it takes a lot of gas to bring your house up even two degrees. I run a non programmable and set our heat at 72 degrees and do not touch it all winter. There should be a water shut off on each rad so if you want your bedroom cooler just shut that shut off on that rad off.
