Oil furnace problem

Hello everyone!
I have a Rheem oil furnace circa 2009 2010. Lately, it will fire up and the fan will start the forced hot air as normal. Before it reaches the desired temp, the furnace will stop firing and I hear a clicking noise until it fires back up again, this process will continue until
the desired temp is reached. It never used to do this and I assume it's a problem, any help would be greatly appreciated!!!

    To me that would indicate the furnace is running up to high limit, and shutting down like it is suppose to do for safety (the fan keeps running, and the burner fires again). But why is it doing that now and not before. Maybe it's an airflow issue, like dirty air filter, or failing blower motor.
    I'm not sure about the clicking noise, if it's not an expansion noise then maybe something is happening in the board or the fan/limit control.
    Either way the problem isn't going to cure itself, and I would recommend a competent oil tech to come over and troubleshoot the problem

    Check your air filter it could be pluggged

    Just changed the air filterin anticipation of finding a solution. I'm starting to think it has to do with airflow too since upon startup it runs fine for a few minutes and then the problem starts near end of heating session

    Maybe it could be something else too that triggers the safety mechanism???

    Make sure your supply and return air ducts registers are not blocked.

    Shut the furnace off and remove the cover for the blower and check the blower

    Anything that shouldn't be there.

    If you could post some pictures of the furnace, that may help. See a lot of poorly installed furnaces tripping high limit due to inadequate ducting.

    Your clicking noise and erratic burner is from the relay on the side of the primary control (where the reset button is). You'll see your thermostats wires to terminals R,W,G,Y,C. You can feel the little black relay clicking when calling for heat. You need a new Beckett A/C ready terminal block, less transformer.

    The air duct work is from 2010 so besides and mice foul play, I can't see anything being blocked. So do people think it's the terminal block or an airflow problem. I checked out the blower, vacuumed a bit but it didn't seem that dirty, just some general dust on the small blades.

    If you have the setup I described, then that is your problem. The relay in the Beckett A/C ready kits fail frequently and the symptoms are exactly what you described.

    Cool any recommendations on where to get a new one? Safety tips on changing it? Really appreciate the help

    Definitely sounds like the Beckett terminal strip. Beckett part number is
    #51Kit terminal Base. transformer delete.

    Sweet people! Where to buy?

    Don't know where you live. Sid Harvey,
    Blackman plumbing supply. Maybe Grainger.
    Take pics of the wiring and the terminals they're attached to in the primary junction box. Probably need some wire nuts as the factory splices are crimp connections. Needle nose pliers.

    Those bare wires need to either be wrapped around the screws, or double the spade connections.
    I also recommend a qualified tech to diagnose and repair your problem. If that wasn't the problem, or you short a component out by wiring it wrong, it will cost you way more than paying someone in the first place.
    And if you buy it from Grainger's...nevermind, do what ya want.

    I won't wire it wrong because I don't rush, I can go slow be safe and learn which is the whole point of this forum, If I get the exact same part and take my time I'm sure I can avoid a short, just want to learn safely about my system without a negative outlook

    That was a setup by a qualified tech when the house was built only six years ago

    Yeah, that's the part. You don't need the transformer but if it comes with, it won't hurt.
    Not rocket science thadri. I have faith.
    Those bare wires are fine, don't wrap around screws, just get them under the terminal plate.
    I don't know what's wrong with Grainger. Must be a Flyers fan.

    Thank you HVACNUT. What do you mean by "just get them under the terminal plate"? I plan to tag each and every wire and use photos to match installation.

    The screw terminals have a little square plate attached. When you tighten the screw it sandwiches the wires.
    Like I mentioned earlier, those Beckett A/C ready kits fail frequently. That's how I knew right away what the issue was just by your explanation. I miss the old fan center controls. Sometimes technology is a bad thing.

    Worked like a charm!!! Thanks to the helpers. Even changed it to the new transformer since I was in there
