Nag-papalit kami sa isang shop ng masmalaking condenser sa sasakyan. Pagkagawa, hindi na ikinabit ulit yung pressure switch at hindi na raw ito kailangan kung malaki na condenser.
Napasilip rin kami sa ibang sasakyan na ganoon rin ipinagawa pero sa ibang shop naman, at wala na ring ibinalik na pressure switch.
Tanong lang, ok lang nga ba na wala ng pressure switch kung malaki na condenser? Hindi ba puwede pang makasira sa A/C ang overpressure? A/C system nga pala is 134a. At the moment parang gusto naming bumalik at ipalagay ang pressure switch.
Inputs appreciated. Salamat.

autobeat,
your pressure switch is installed to cut clutch operation when there is low pressure and when there is overpressure. the logic behind cutting clutch engagement on low pressure it to prevent damage to the compressor. if the refrigerant is low, it follows the oil is low too, and to prevent compressor damage, it will cut engagement. in that way too, if the charge is low, there will be little or no cooling. the logic behind the high pressure cutout is to prevent rupture of the hoses and seals. that shop is partially right but wrong, it will operate at high risk. find another shop and avoid this one

Thanks, Jick.
Yes, will try to have the shop restore a pressure switch for our A/C system, else will find another shop that could.
Thanks again for the reply.

ok lang na walang pressure switch para pag nasira compressor mo babalik ka sa kanila hehehehe...pde naman sa dryer/receiver ilagay yun pressure switch.
Be careful with channels like "China Observer" on YouTube. There is a clear bias in their posts and...
