HELP!! I got a problem with my A/C

Ok, my when I turn on my A/C, it starts but pulses slowly insted of fully turning on,and every time it pulses it slightly revs the engine then stops then repeats, the air that it puts out is barley cooler than with the A/C turned off so it's useless.

I looked at the pdf file page 20 of page 124 for t-stat says for a Y594g1476 to remove the jumper IF W1 is used. I don't know if you have 2nd stage of heat such as electric heat. I would check wiring according to your outdoor unit and indoor unit and the t-stat. At the very least you will need R and it looks like X terminal giving you the 24 volts. for the control circuit. O is for the reversing valve. G for the blower. Y for the compressor contactor. W1 goes to the fan section to operate 2nd stage heat if you have it.You can also remove the t-stat and make sure you have the correct subbase which the PDF file shows for a y594g1476 stat it should be a Q674 series. Also what you can do with the stat off is jump out R to G to O to Y that should bypass the t-stat and bring on the fan and compressor contactor and the reversing valve. ( reversing valve is energized in the cooling mode ) see what happens ,you may have a built in 5 minute timer before it starts.I was unable to find the PDF on your Tempstar. So I am not sure what the outdoor coil temp. sensor is. I know that to initiate a defrost heat pumps use an outdoor sensor strapped on the outdoor coil bend. it usually labeled DFT (defrost thermostat ) but that should only work in the heat mode. Also they may show an OPITIONAL outdoor sensor/stat to stage 2nd stage of heat if using electric heat. But as far as I know that is installed by the contractor and is optional. In closing I would double check the control wiring from the t-stat to the outdoor unit to the fan section. Then I would bypass the t-stat with the method I told you. You can also take it one step at a time R to G blower fan starts .R to O reversing valve energizes. R to Y compressor contactor closes (after 5 minutes).Also the PDF shows an optional outdoor sensor that hooks up to the thermostat. If your handy with a volt meter check that you have 24 volts between R and X terminal at the stat

Starting Problem


Fully charge the battery and see if it starts like it should. If your battery is fully charged, but still turns over slowly, its your starter. If using a fully charged battery solves your problem, its your alternator.

Something is very wrong with the camshaft (lobes worn down?), or the oil galley to the hydraulic lifters is blocked or otherwise has inadequate pressure. I initially considered a broken cam pulley key or slipping belt, but that seems to be ruled out by the distributor rotor turning - it is driven by a gear on the camshaft. It's possible something has slipped out of time - check the timing marks on the crank and cam pulleys, and verify that the key slots on the pulleys are lined up with the key slots on the shafts.
