I'm trying to find a replacement part for my honeywell s400a feed timer. I know they are phased out but I am finding it extremely difficult to find a replacement part that would be suitable. I have a EFM I believe it's a 520. We use Rice anthracite. Any help in a suitable replacement part name would be so great. THANK YOU :D

Welcome. Your timer is obsolete and parts are scarce. I would replace the timer with a new one.

One of these would be simple to hookup:



If you are looking for something at a lower price point and are comfortable with the wiring, one of these will work also:
