I have a Weil-McLain oil fired hot water furnace which is cleaned and

it will do that again. *It doesn't sound like its failing and
stopping, just stopping normally.

I am assuming there is some part or component that may be causing this
but because I'm not a furnace guy I thought I would ask here before I
dig further. *We do have four zones plug a hot water heater connected,
each with a separate thermostat.

So, any suggestions as to what it might be?

Thanks

Get whoever serviced it back. This is not normal.
