A heat pump compressor will freeze if the refrigerant levels are low or the outside temperatures are too low. This will cause the pressure to drop inside the system and temperatures to plummet.
The exact same thing it does in the cooling mode, the change between modes of operation does not take place in the compressor.
No. The compressor is needed to run in reverse in order to pull warm air from the outside to heat the home.
There are a few reasons a vehicle is overheating. The common causes are the thermostat, water pump, radiator, or the fan stopped working.
It could just be that the water pump is not properly working. Have you checked all the could-be causes for your car overheating if not then do so.
Heat pumps use a compressor to make the working fluid condense at a higher temperature.The compressor needs input energy.
Possible causes: Insufficient/no coolant in the system; insufficient antifreeze in the coolant and the coolant is frozen: the water pump is faulty and is not circulating the coolant; the belt that drives the water pump is loose or missing.
a 2002 Alero could have several problems causing the overheating. Thermostat, water pump, or clogged radiator issues are the most common causes of overheating.
Sure, just look on craigslist. Everything is on there.
The compressors are basically the same . Very simply put with out getting to technical is what makes a heat pump a heat pump is a reversing valve that changes the direction the refrigerant travels in lines leading to and from the condensing unit and to the coil, without changing direction of flow in they compressor. You should always check with the manufacture before replacing an unlike compressor for compatibility.
if v8 it is usually water pump. rarely is it the thermostat.
low anitfreeze, no water, busted headcap
