Having Problems With my Burner

[grasshawg]

I was washing away this morning and suddenly I noticed my water was cold. I had just filled the tank w/deisel the day before.
Switch works fine. Power to ignitor. Fuel filter not clogged. The blower doesn't seem to be picking up fuel, and the blower motor is not kicking in. What could be the problem?
I had to finish out the day with cold water. NOT good on logging equipment!
Help! I need to get this fixed this week, or I'm in deep doo-doo.
Thanks
Randy

It's your solinoid. I think.

Randy,

12v system or 115 v system? It would also help to know if it is Beckett or Wayne.

Generally, most units are wired so that when the burner control switch is on, it powers the blower. If the blower is not working check 1) is the motor turning and not the fan (squirrel cage), there is plastic coupler between the two and it may have broken. You should be able to look through the squirrel cage blades and see where it attaches to the motor shaft. 2) if the motor shaft is not turning check the little reset button on the end of the motor so see if it has popped.

Also check to see if the squirrel cage turns freely by spinning it with your finger, it should. Just in case something has it bound up.

Depending on your set up, the fuel solinoid is controlled by the pressure, flow, or vacume switch. That is what cuts off the fuel when you release the trigger.

Good luck,
Doug

Randy,

If you tried running the burner with engine
at less than full throttle you could have tripped the
blower motor reset button. Usually found on end of motor.


Try resetting the button, it is usually a little red button
on the blower motor. If all else fails I am only a phone
call away Buddy! After hours dial 208 and it will forward
to my cell phone.

Usually your pressure or flow switch turn on the fuel..... Pressure switches fail more often than the flow type...

Sounds like solenoid.

 

[Mark]

Randy,

Let me know if it was in fact a tripped
reset on the blower motor. [hello]

 

[grasshawg]

Mark, no tripped reset.
Doug T., fan does not turn freely. I'm going on a small wash job today (1 bobtail truck). I'll examine everything more closely while I'm there. More to follow. Thank you, evryone.
Mark, I'll call you later.
Randy

Randy,

If the blower motor is not turning but you have
spark at the transformer, I would suspect a tripped
blower motor. Question is what caused it to trip.

Possible Causes Include:

-1- Low voltage to burner.
(on your unit you should have 115 -130 volts from
generator when you have throttle on your Honda
wide open to the stop.)

-2- Fuel pump drag.

-3- Fan / squirell cage dragging on something.

I will call you in a few minutes...

 

[grasshawg]

Doug T., Sorry about that. It's a 115V Wayne Motor.

Randy,

Glad we got the blower motor working,
in the morning check fuel solenoid power cord,
it may have been knocked loose when we were
troubleshooting this evening.

The power cord plus in to the fuel solenoids coil housing.

 

[grasshawg]

I checked that after we got off the phone. The plug is intact and was plugged in securely. However, what is the small nut for located on the very front? It was a little loose and there appeared to be some corrosion behind it. Also, when you grab the power plug, should it move at all? It will spin around and around if it weren't plugged in. Am I clear on that? It's hard to explain.
I'll tighten that nut tomorrow and give you a call when you get to the office. Thanks again for all your help.
And to all you others also.
Randy

 

[Mark]

Randy,

The nut you described holds the coil (electromagnet)
to the solenoids valve body. You should read power
with your multimeter from the plug, unplug the cord from
solenoids coil assembly and see if you get 115 volts there
when you pull the trigger. The pressure switch completes
the circuit sending power to the solenoid when you pull
trigger.

Let me know your findings in the morning.

Mark/Randy,
Curious, why wasn't the blower motor running?
Doug

 

[Mark]

Reset button was tripped.

Mark/Randy,
Curious, why wasn't the blower motor running?
Doug

Could have something to do with operator head space! (LOL) I think I was looking at the wrong thing when I said it wasn't turning freely. After a little more coffee, I'll go outside and check that selenioid.
Thanks, Randy

 

[grasshawg]

Turned out to be the pressure switch. I appreciate everyone's assistance.
Thanks, Randy

 

[Mark]

Randy,

I shipped the pressure switch VIA UPS
Next Day Air, you will have it Tuesday! [hello]

 

[Mike Gwas]

Those pressure switches are useless..... Have Mark send you a flow switch instead. Also do not put on one that needs to be in the upright position (another piece of junk)......
