We have a Onieda Royal OIL furnace we purchased in 1996 that will not start for a few days ya push the reset button after waking up to a cold house and it would come on .But this morning that won't even work .We cleaned the power venter pipe and changed the nozzle .What else can we do to get this running???

It is very hard to advise on an oil furnace. Allot of specialty tools are needed. In my experience there are allot of service men who have no business working on them.

Call a qualified service person. Could be a weak ignition transformer,electrodes,plugged oil filter etc.

If you are going to get it going over the weekend, you are going to figure out the start up sequence and what isn't happening. It may or may not be something you can fix. Is the oil flowing? If not, why not? Are you getting ignition? If not, why not? Does the blower come on, etc.

Service Man came and found the vacuum switch for the power venter inop. So that is good to know especially since were suppose to get a foot of snow tonight. Thanks for the replies.
