It's a lennox pulse mounted horizonally in about a three ft. high crawl
space. I think this'll be it's 8th season to heat........ maybe ten ??
It's been a pretty good replacement for the old oil burner that i'd
gotten 20 years average service out of .... But .... it's not been
completely trouble free either :-( In the past four years it's had
grimlins in it. No ....... one repeated it's self.
I need to say that I had my programmable Emerson thermostat ( bought in
'93 ) that was used on the oil burner installed on the Lennox when I
the furnaces were swapped.
Now ..... Into about the third year of service, my Gas / Appliance
dealer sold out to a larger company ??............. along about then is
when the blower on the Lennox started to ocasionally
"run on " , best I remember we couldn't stop it running at the
thermostat ........ had to go kill the main power at the breakerbox.
I got up with the ex-dealer and he told me to put a couple drops of oil
on the limit switch shaft where it turns in it's pivots ........ This
seemed to help, but by that time heating season was over, and the
Moncrief AC, combined with the Lennox blower did a great job all
Then I believe I had a trouble free heating season.??
That gets me to last year, more than once I'd have to tinker with the
thermostat and finally the main breaker to get the burner going.
Again a trouble free cooling season in '06
Now, into this heating season,'06 / '07 the burner is failing to start
again. I've replaced the old
Emerson programmable thermostat three weeks ago with a solid state non
Now, ocassionally, without touching the thermostat, I've had to go to
the main breaker box, shut the power off and back on........ wait for
the min.or two for the burner to fire and run ??
Hope I've not left anything out ?? .... The need for turning off of the
power is what's puzzling me ??
Any Ideas out there?
Much Obliged :-)
