problem about thermostat...pls help!!

[umzzzzz]

hmmm...thermostat is yung nagkakabit mula radiator hose to water pump right? yun po ba un? umiiral nanaman ang pagka noob ko eh...

[jayelgee]

diba thermostat ng aircon yung nagreregulate ng lamig sa cabin...

I agree with you.. kaya pag walang lamig you have a leak.

[key7wizard4]

yup guys,sabi nga nung tech is bka may leak daw...alin ba dun ang pwedeng mag-leak?

[alwayz_yummy]

honestly, for me gingoyo ka nung pinagtanungan mong yon....

1.)thermostat na tinutokoy ay hindi pwede at hindi kailan man pwede maging source ng leak.kasi, no gas na dumadaan dito at kung original pa theremostat mo makikita mo lang yang may rod na nakatusok sa evaporator mo at 2 wires...it acts a switch for the compressor kapag nareach na ung desired coldness ng evaporator...

2.)ang posible leaks lang commonly ay sa fittings, maaring may sirang o-rings or di maganda ang pagkakasalpak lang ng mga yun..

3.)ung pipe leaks mostly due to high pressure or too much bending of the pipes.

4.)evaporator only leaks kung nilinis gamit ay ung LYE, pero di masyadong binanlawan..ung natirang LYE will react on the water that the evaporator will produce and in turn mabababad sa evaporator which will eat out the evaporator's soft aluminum structure.

5.)baka due for replacement na ung expansion valve and "reciever-dryer", kasi in due time, nagbabara din ito because of dirt na nakapasok sa open pipes while servicing the aircon-system.ang masama nito, kapag pinabayaan mo, maaring cause ng pag-babara ng pipes which will make the compressor work much more that it need..

6.)compressor naman nasisira kapag napapabayaang madumi ung system, when releasing freon, di nirereplace ung oil na nawala, which may lead to pagkonti ng oil sa compressor...

halos lahat ng dapat maexperience sa aircon, naranasan ko na,e...un lang di ako kay mang mario nagpapagawa, dito ako sa may lampas pa ng tandang sora ave, along mindanao ave..tago ung lugar at talagang sadyain...si "mang ernie" naman ang pinupuntahan ko dun..

ngayon ung liteace ko naman...7500 ang quote sa akin dun used a slightly bigger nippon-denso compressor(di ko maalala ung model,e) na ipapalit(kasi dual aircon liteace ko+cold and hot box).. kasi ung compressor ko halos di na pala bumubomba, complete na din un job(freon, cleaning, flushing ng pipes,condenser and evaporators)..

kung may makakapag PM sa akin ung exact way papunta sa kanila, sadyain ko sila..dito lang naman ako sa proj. 6,e, 2nd expert opinion ika nga..(sorry sir key7wizard4 sa konting pag-sawsaw sa thread mo, ha?)

ok lang Bro dapat nga magpasalamat ako syo e,*least may mga pointers akong nakuha syo,someow dami ka na rn pala alam about a/c problem,bka dalhin ko na lng kay Mang Mario 2ng sa akin...tnx Bro

welcome....salamat sa surplus ng japan na binaboy ang pag-convert....sa almost 17-year-old maxima, at eto ngayong ride ko...and a hefty amount of money kaya ako natuto ng ganito...

puntahan mo na din, at baka magkita din tayo dun kung sakali..

nga pala, kung light repairs sa a/c system ng rides ko, i DIY it...(makatipid ng sa labor and parts,e)

[nixon75]

mahal aircon parts, in your case baka leaks lng sa tubes. they can always test the lines naman. kng thermostat daw ang problem then minor lng yan. it jst controls the temperature in the car. hindi nare-repair ang thermo, replace na talaga. pinakamahal parts ng aircon ang evaporator, condenser at compressor. evrything else medyo mura na.

[nixon75]

umzzzzz: thermostat ng engine yun, same function with the aircon system's thermostat, regulate ng temperature

[quiksie]

ako nagbackjob ako after palinis aircon ko. May hinigpitan lang ata sa condenser. Sana hindi compressor yun may deprensya. I need to check pa ng ilan gamitan kung hindi sira ang compressor ko.

Ang tagal nga bago mapinpoint yun sira sumakit tuloy tiyan ko hehe

[key7wizard4]

salamat Nixon & alwayz yummy...

Thanks, Yummy, for sharing with us your knowledge and experience.

I have a Mazda sedan 323 1966,the one used for taxis.

The compressor would not turn off, so its gets cooler and cooler in the cabin. What I do is to switch off the aircon and then on again, to avoid having the cabin getting too cold, but the aircon blower on the dashboard I keep it blowing.

I asked the service shop owner who works on my aircon every eight months about the problem. He told me the thermostat switch is bad, and he will connect a new switch splicing it on one wire from the old switch, and inserting its fine copper tube with pinched end into the fins of the aircon evaporator. Price for both switch and labor is P750.

I think if I could reach that switch that is supposed to be bad, I might repair it. I am one stubborn person for DIY repairs.

I called up another shop and the owner said it could be one of five relay switches being busted, or worse the compressor bearing worn out. Relay labor is for him P600, replacement of bearing for compressor is P2,000.

For the present I just get along with turning on and off the push button switch for the AC on the dashboard, of course keeping the blower fan on the dashboard on.

What do you say, Yummy? You also do repairs yourself.

Do you think it could be as simple as spraying the out of order thermostatic switch with unlock spray lubricant from aerosol canister?

If only I know where that switch is located and can reach it, without tearing the car engine compartment apart...

Thanks for any advice and maybe you can think about the problem and also ask around from aircon repair guys you know.
