Furnace clicks multipal times while running.Is this normal?

Ok - let's back up a little bit.. Do you have a forced hot air furnace? Does it run either oil or natural gas (or liquid propane)? Do you have a chimney or power vent?

Make sure the kit included smaller sized orifice's and spring kit for the gas valve. The number on each orifice should be cross referenced with total btu's rating of the furnace. It does seem like there is too much fuel or not enough air intake (combustion air). The inches of W.C. seem fine, but you still may be getting too much volume of fuel with too large of sized orifice's. Hope that helps

check out the pressure switch if fitted on this make .

Flame sensor might need cleaning and check connections Also check pressure switch .

Fan control could be on summer switch. or af control not working keeping fun running

first thing i would do is follow the short rubber tub from the draft switch to the furnace. pull the hose off the furnace body and run a paper clip, or such, into the hole. replace the hose and see if that helps. check the vent ing for blockage and then replace the switch

Hi, new switch can be found on amazon... here: Amazon com Coleman air switch. I hope this was helpful. Cheers

It's the pressure switch on the unit. Make sure that the pressure switch doesn't have debris in it that keeps it from operating smoothly. Take the tubing off from the inducer side and breath in and blow out lightly while listening for a clicking noise. If that doesn't work then I would recommend replacing it. That should solve the issue.

Small blower motor? Are you talking about the combustion blower if so then check your vents for blockage.. if the vents are blocked won't work... if it has a control board init it will give you a diagnostic code. Flashing light on the board... count the flashes and look up the fault on the chart in your owners manual ot on the furnace door..

Combustion switch is your vent safety.. Check your vents outside for blockage, sometimes the intake pipe will freeze or frost up not allowing the preassure switch(vent safety)to close. putting furnace into a lock out.. you can reset the furnace by turning the power on and off.. if there is no power switch just remove the bottom door and reinstall...
