呢排好黑仔。
尋晚個車房門開唔到，開咗少少就唔上唔落，急call人整，整咗不過無咗盞燈同埋個地sensor唔work，又要整過。。。sigh...

i guess the electrician  provides warranty for the job?

fibbi

Only if he returns my call.

手工好差喎, 你搵邊間, 叫D老友記唔好搵佢地

無計，夜晚急call嘅都係喺報紙啲Ad隨便篤一個。真係無期望。
而家個safety sensor壞，要換個motor，又＄300幾。唉。

safety sensor壞, shouldn't need to change the whole motor gar..  why?

車房門開小小上唔落，應是斷回力彈弓或拉力威也鬆了。
你第一次換了什麼？

盞燈唔著？是否燒燈泡？咁個motor有冇動？若sensor壞　（學B2L2講，咪換sensor囉，幾十蚊）．　是否只係撞歪咗，或鬆咗線？

你按制開門或閉門時，motor有冇反應？有冇啲答啲答聲？

冇理由咁啱一齊壞？!!!

(assume we are talking about your own house garage)

These garage doors could be easily detached from the chain (which connects to the motor).  Talk a look and you should have a red string with a pull handle.  Once you pull it down, the garage door detaches.  After this and if the rail isn't damage, you should able to move the door up/down manually.

If it happens again, you could simply pull it down manually first and don't need to call for any emergency service (usually double the charge).

B2L2所提的方法，是MOTOR唔郁，燒了的情況是可行．

若你的車房門是細門（一架車濶），你的門有一條回力彈弓，若斷了，你要非常大力，才能由人手開門。
若你的車房門是大門（兩架車濶），你的門有兩條回力彈弓，通常斷的是一條，那時，門的回拉力只在一邊，門會斜JAM死在軌上，你是人力拉不開的．
若是拉力威也斷或鬆了，就點都不可以用人力拉開門．

Satil is right...my garage is 2 car size garage door...
最初，一條彈弓斷咗，靜返一條，嘗試過人手開不過唔得，adjust過個motor(tune up the sensitivity or power level)，開到，不過落嗰時個閘出咗軌，條軌都坳咗，所以個閘唔上唔落。其實個motor無問題。
到佢換咗條彈弓，個sensor同盞燈唔work。
next day 我叫咗另一個handyman嚟整safety sensor，佢check咗之後話要換個motor，我諗佢係話個logical board唔work所以要成個motor換。

仲慘嘅係，頭一個人嚟整嗰時，整爛咗我放喺旁邊嘅summer tire，我有個架嚟鎯住啲tire，佢唔知係唔係用嚟借力，壓爛咗我個tire 中間嗰個cover仔。又唔見多二三十。。。
