Low to zero pressure on low side test port


150 is low for high side pressure. may have to add more r-22 to system. if you had a blockage high side pressure should be higher. have you turned both service valves at condensor ccw completely?

Bad condenser unit GOODMAN


it is a 3 ton condensor you still can buy r22 freon condensors new but they have nitrogen charge and its expensive to charge I recommend to go with 3 ton goodman condensor which is new 410a puron and also change indoor coil and flush the line set so you dont endure the high cost of new copper lines these new systems come with 10 years warranty and the r22 systems come with only five years

Not cooling good


while the machine is running, partially block the outdoor fan until the high pressure reaches 270 psi, the low pressure should be 70 psi at this time. This should be true within 10 lbs.

Pressure in both lines fluctuate from 140psi to below 30psi


The foreign made market is different than the USA.

First if the unit doesn't get a change or input from a manual command (on the remote on mine) it will shut off because it assumes there is no one there.

2nd if it is in the timer mode it may be different in orientation than what you are used to looking at.

TO make sure these are not your problem review the instructions.

If this is R22 or R410A there is not a pressure switch that will cut it "OFF" at 140#. And if your fluctuating tween 30 and 140 It is almost sure its low on charge especially if its new. Now I assume you mean 140 on the high side, right?

Two lennox heatpump 71/2 tons


check the true psi with the line psi to see if same if psi is good in cooling 225 hi and 70 low on 80'day then compressor is fine and i would start checking for temp difference on the reversing valve sometimes this will cause high suction or high discharge psi shift it manually with by energising it be cooling or heating then pull wire and see how it shifts if shifts good then txv on out door unit could be bad what is the psi in heating on the discharge line going to the indoor unit? most prv's are set at about 350 psi r22 as for suction line size its only hot gas in hp mode os no problem their shows in cooling mode as low suction psi ..hope this helps some also make sure indoor coil is clean!....thanks & rate me
