Re: Modern Omron G5L-UA-006000 Relay

Just an update. Ended up solving the failed receiver problem by installing a Solidremote #202U version 6d remote RF relay switch. This remote RF relay switch has two SPDT relays on it (two channels), and just hooks up in parallel with the wall switch using the N.O. contacts of one of the relays. The factory default of the unit is set to momentary contact, so it is was all set right off the bat. It seems very well constructed, and was fairly inexpensive. Without a schematic of the logic board of the garage door opener, this just seemed like quickest...

Re: Modern Omron G5L-UA-006000 Relay

Cleaned K1 (down relay), & K3 (power and light relay), with no real improvement. The covers snapped off easily on those (which are Omron #G5L-UA-006000). The other relay is K2 (Omron #G8P-114P-FD-US), which is the down relay. That one looks like the cover is sealed. I didn't take that one off the board yet. It did have carbon marks around the base, which I cleaned off with window cleaner. The number on the component side of the board is #14LG0500B which I found on a site that rebuilds these, and it showed an Aromat #JT1E-DC24V-H24 relay...

Re: Modern Omron G5L-UA-006000 Relay

Thanks for the suggestions.
There has always been an old school bulb in it, and the light socket has been cleaned. These light sockets, being just plastic, always seem to be a problem in these units. The remote works fine, and has good range, when the light is off. So I am pretty certain the receiver section is fine. There are new batteries in the remote as well. There are no new sources of possible RFI in the immediate area, either. The light relay also feeds power to the motor through the other two relays, so it does some heavy lifting....

Re: Modern Omron G5L-UA-006000 Relay

I am just wondering if anyone found out where to get this original Omron relay (G5L-UA-006000). There are two of them on the garage door opener logic board I am looking into, along with one other Omron relay (G8P-114P-FD-US). These relays seem to be obsolete, along with the logic board itself. The problem is when the opener light is on, the remote does nothing unless I hold it right up to the antenna. The wall control and remote work fine otherwise. A very common problem, I understand. I have yet to see if I can clean the contacts on the relays....
