List of which remotes to use with old garage door openers

[Sav]

Desperate to replace remote control for my garage door opener: Chamberlain Doormaster 420 (1993); model 420ED Installed in France therefore need remote control that's compatible with European frequency. Any help greatly appreciated.

Hello

The remotes for that unit are now discontinued we now have an RX1 package deal which consists of a universal receiver and remote, we provide a wiring diagram for the unit, if you take a search RX1 on our manuals page it will give you the simple wiring diagram, so you can take a look before you buy, your old remotes will still work on the system, we also offer assistance on the phone if you would like to call us,
