Anybody experience this on their A/C system

Lately, I have this problem with my A/C compressor.

Kapag naka on yung A/C at warm-up na yung makina tapos naka idle yung oto, yung compressor eh bigla na lang nag on/off ng tuloy-tuloy. Para bang clik, clak, clik, clak, clik clak na tuloy-tuloy yung compressor, this goes on for about 20 seconds and only on idle.

Pero kapag umaandar na yung oto, nawawala na. Pero pag cold-start tapos on ng A/C wala naman. Pag medyo malayo na yung natakbo ng oto saka lumalabas sudden on/off ng compressor kapag naka idle.

Saan po kaya ang problema?

Thanks

Thermostat control diode. This could be your culprit, kaya nag on-off simultaneously ang compressor. It is located near your evaporator inside the vehicle. Siara na yang diode kaya nalilito sya kung on/off yung compressor mo.

Hehehe, ayush! Galing ko talaga mang-hula. :mrgreen:

Kidding aside, naranasan ko na kasi yan dati, pinikon ako ng aircon ko. :D Ginawa ko pinatay ko na lang and opened my windows while trucks and jeeps polluted my nostrils. Went to an airson specialist and checked the busted diode, mind you this is not a cheap part. They charge a fortune for this small black piece. :idea:

ako din mukhang may problem a/c ko after cleaning. paminsan minsan specially kapag tanghali ay tutunog ng ehhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh the first time na i on the a/c pero mawawala siya kapag on off ko yung a/c for a few seconds. after that wala na dahil parang nakawarmup na siya. ang masama kapag balik ko sa nag-cleaning ay di na magpapakita ulit yung problema dahil nga nakawarm-up na. they suggested na na overcharged sa freon and that's what i'm thinking too so bawas ng unti. mga 1 month ay nawala yung symptom then suddenly ito na naman siya. the thing is hindi madiagnose maigi kasi kapag dating sa aircon shop ay normal na ang a/c ulit. ano kaya problema, i'm thinking na baka kulang or wala langis na nakarga. baka matulungan nyo ako. ty

Galing ba sa blower yung sound? Or yung singaw ng cold air from the evaporator? I could suspect that your blower need some bushing replacements or in other vehicles bearings.

salamat po sa mga reply, I'll have my thermostat control diode checked.

thanks :D

Glad to be of help artpogi! :D

Just a reminder though, summer is fast approaching you may want to have your freon refilled and have those evaporators washed. You don't want to drive your vehicle with an aircon that fills more hot air in it.
