AC blow air, not cold <— fixed

first time replaced this thing called capacitor. AC is back!blowing cold.
took the time checking if drain line is clogged; checked again the air filter making sure I wasn’t stupid in placing it in wrong direction; cleaning the outside condenser fan unit.
I was researching into this thing called capacitor, claiming 90% not blowing cold due to condenser unit wasn’t on.
tried to test to confirm unit is indeed bad. multimeter Ohem testing showed some resistance btw fan and ground, but nothing btw herm(?) and ground, suggesting the capacitor is bad. I am not able to locate a tool that test capacitance, inexpensive and I can get it today.

online has the capacitor replacement for under $10, but figure ACE nearby has it though $26.

tested again the new capacitor, both fan and herm showed some resistance data change suggesting good.

replaced and put correct wires, which I took a pic and also wrote down: blue to herm, orange to fan, two yellow to ground.

power on.

thermostat set to lowest which is 65 f.

felt the cold air from bedroom vent; felt warm air from the condenser top, cold on the 1/2” copper line.

whew, I made it.

• 鼓風機的run電容在furnace裏麵，有的在control board後麵鐵板的背麵。容量一般隻有幾個mfd. -hellotom- ♂ (63 bytes) () 07/23/2023 postreply 11:11:20

• 這個是空調啟動電容。空調與製冷有關，與暖氣無關。管道的風是靠fan, fan基本不會有問題 -qtsx- ♂ (0 bytes) () 07/23/2023 postreply 08:39:24

• 電容上不要省錢。不要買雜牌。第一美國造的，第二墨西哥造，第三買品牌的。遠離中國造雜牌。這個牌子希望能使用超過2年。 -PrimeryColor- ♀ (0 bytes) () 07/23/2023 postreply 15:13:26
