Please help me. I don't know what to do. After a short vacation, my oil
furnace won't turn on automatically for hot water. Nothing else changed.
My home has a 19 year old oil furnace which says Burnham RSM-126 on a
plate. It will not turn on automatically for hot water.
I have to keep hitting the start button to make it turn on to heat the hot
water.
This problem started after I had the water and furnace turned off for 2
weeks while I headed off on vacation.
Any suggestions on how I can troubleshoot this on my own? Or is this one
item which isn't home testable since it involves oil?

This is a boiler, not a furnace. Does the boiler run if you turn up a
heating thermostat? What "start switch" are you referring to? If you are
talking about a red button on the burner primary relay, the one that says
something like "push only once", you need to get an oil burner tech out.
That's a safety lockout telling you that something is malfunctioning in the
burner. Resetting it multiple times can be dangerous
