Have a 7 year old Tecumseh compressor cooling
Constant cycling AC unit. Hermetically sealed. 1/3 hp.
It worked "good" (ie, a bit noisy, but colder than a mother-in-law's kiss) until I accidentally left it off for a week. Now I can't get the darn thing to start.
I checked the capacitor and circuits. All okay; I installed a new capacitor just in case. The motor
hums, but when it tries to start, it makes a grumbling sound, but doesn't kick in.
Is it time for a new one?
This wouldn't be caused by low refrigerant, would it? (I'm only asking because it's been a while since I checked it)
