The general cause of this problem has to do with limit settings being set incorrectly or clogged-up
safety sensors. Check them for dirt or misalignment and clean them. Other times, adjusting the limit
settings as instructed by your manufacturer can resolve this.
Noisy operation may be due to loose hardware, worn rollers, or lack of lubrication; keep the bolts and
nuts tight regularly, lubricate the moving parts regularly using proper garage door lubricants and
replace
any that are worn out. Due to this noise, the opening and shutting process tends to be slow. Such
malfunctioning could be due to spring and roller wear and tear, and hence proper action in replacing
them
by the doors technician is necessary for smoother operations.
Complete Failure to Operate: If the opener doesn't work at all, check if it's receiving
power. Check
the
circuit breaker and ensure the unit is plugged in. If the electrical issues are out of the way, then the
problem could be within the motor or internal circuitry, which requires a professional to attend to.
Dealing with these small problems in time will help avoid further damage and elongate the life of your
garage door opener.
