SOURCE: Does the lemon law cover air conditioning units?I

as a general rule the lemon law does not effect acs. because the equipment colud be at fault, or the installer couild be at fault , or the installation or application coiuld be at fault, or the power company could be at fault or the ductwork inadquete or undersized? so there are so many variables that a new ac may not fix your problem so they rarely ever provide new.now lets discuss your insatller or dealer. why are they saying the rev valve is bad? let me say covs Changeover valves usually do one of three things. they stick in cool and wont shift so youare stuck in cool or sruck in heat. when energized you hear no kawhoosh sound and compressor doesnt change pitch. then they are stuck in heat or cool. what they do sometimes is stick halfway and that gives a coolish suction and a coolish line to the house but not real cold. the hot gas line is only warm and the discharge line is onlty warm. this means its stuck halfway. some times you can disconnect the fan run the pressures way up and gently tap the valve and it will free up. but it nay stick agagin. the valves in the compressor may also be weak and be misdiagnosed as as half stuck covalve.. you could close off the liquid line and see if the compressor cah pump down to zero . if it can't then compressor maY BE BAD .when the unit was installed did they put in a liquidline drier to collect impurities and protect the valve? its pretty unusual to see a valve fail and if to much heat is applied on replacement then new valve can be damaged. good luck , oh you have the option of requesting a different dealer if it is brand name like trane or american std with a parts and labor warranty. most dealers can honor the other guys warranty and get paid by the factory if you have lost confidence in your guy. i am sure you know right away if you got a budget jack leg job or a pro . good luck.

No this is not normal. You have a problem refered to as "short cycling". This is an indication of low refrigerant charge. You need to have the unit leak checked, repaired and recharged,

SOURCE: looking for manuel reset on heater amana ptac

I have a Amana PTAC Model PTH153A50AC with the DigiSmart upgrade kit (DSUK01B) which as of last night stoped generating heat. I tried the Diagnostic and got a "LF" displayed. But I find no reference to what LF means. HELP please. Also I looked but can't find a reset button either.

Press and hold up and down arrow at same time -press off twice to get into program mode (should read C1) -press heat button to scroll to C2 the use up arrow to scroll through options. You want to set it to read-out "On" then press off to set. This should be the continuous fan mode.
