Comparison of the LiftMaster 8355 and 8550 garage door openers

LiftMaster Series

The 8550 is part of the newer and more modern Elite series while the 8335 is part of the more basic Premium series.

Mounting options

As Jackshaft door openers, they are meant to be mounted on the walls rather than the ceiling. This wall mount option offers unpretentious yet reliable style for homeowners with low ceilings and minimal headroom.

Engine and power

LiftMaster 8355 vs 8550

LiftMaster 8355

While the 8550 is designed with a 12V DC motor, the 8355 has an AC motor. This makes the 8550 more energy efficient as it consumes less power than the 8355. The engine of the 8550 is also equipped with more power than that of the 8355, making it the most powerful product.

Despite this difference, both engines have belt drives that ensure quiet, smooth, and maintenance-free operation. Purchasing any of these Lift Master products gives you reliable, powerful and durable motors.

Backup battery

Recent versions of the 8550 come with an included or built-in battery backup system that kicks in in the event of a power failure. This ensures that the opener continues to operate without power. The backup battery comes with a one year warranty period. The 8355, on the other hand, does not have a battery backup function and therefore would not work in the event of a power failure.

Internet connectivity and 828LM Internet gateway

Both openers are designed with patented LiftMaster MyQ technology which allows your smartphone to monitor and control your garage door and turn your home lights on or off. This feature also ensures that users can receive email or SMS alerts informing them of the current status of their garage doors and home lighting. However, for full functionality, a LiftMaster Internet Gateway must be purchased separately and installed to work with the opener.

For both openers, the 828LM MyQ Internet Gateway is a recommended choice. It is essentially a two-way communication system connecting the door opener unit to the MyQ mobile app on your smartphone, tablet or computer.

Security

A key safety feature found in recent models of LiftMaster door openers is rolling code technology, and the 8355 and 8350 are no exception. This security feature ensures that a new access code is sent to the opener each time the garage door is opened. This new code would be used the next time the door is opened and then changed again for the next time. This cycle of forever changing passcodes helps prevent eavesdroppers and hackers from opening the door once they get the code you just redeemed because once a code is redeemed, it can no longer be used. Rather, a new one is sent to the opener for the next entry.

The PosiLock feature of both garage door openers also ensures that the garage doors remain locked and secure in the absence of the owner. It does this by electronically monitoring the door for any sign of an attempted break-in, effectively locking the door and preventing it from being forced open.

protection

LiftMaster 8550

Both openers are designed in such a way that if during closing the door comes in contact with a person or object, its movement is instantly reversed. In addition, once the door is in motion, a security sensor produces invisible infrared beams on the doorway. If a body or object crosses the path, the beams are interrupted, immediately alerting the opener to the presence of a person or object in the doorway. The opener lights come on, the opener stops the progress of the door and reverses its movement.

Timer to close (TTC) and close alert function

The LiftMaster 8550 has a built-in Timer-to-Close feature. With this feature, users can program a setting on the accompanying 880LM smart control panel, requesting the door to close after a specified period of time if it had been left open by the owner. It also gives audible and visual warnings once the door is about to close, informing anyone in the vicinity to stay clear of the door when the door is closing.

Compared to the 8550, the 8355 does not have this built-in timer function. However, its 882LM control panel gives audible and visual alerts when the garage door is about to close.

guarantee

Both LiftMaster openers come with a lifetime warranty on their motors and belts. While the 8355 comes with a one-year warranty on other opener parts, the 8500 comes with an impressive 5-year warranty on its parts.
