I apologize I did not thoroughly explain myself. The whole purpose of sticking a paper clip through the orifice is to clear out any obstructions. After removing the paper clip and the burner lights...

If you could get in situation where only one burner lights next time I would take one end of paper clip or something small and stick up through the next orifice not lighting, then i would initiate...

Sounds like something in manifold assembly intermittently clogging up one of the orifices. If one burner does not light due to clogged orifice the other burners in line with it will not light either...

Sounds like loose connection somewhere. I would get someone more experienced to check it with you ,no use in taking chance of burning house down due to wire getting too hot

Build big bon fire around unit and it will keep the thing from freezing to death

I wonder what the surface temperature was at the location where the sequencer was mounted? Also at what temperature does the sequencer contacts close..... This calls for an all out investigation...

What was the original complaint? Or was this just a maintenance call?

You are awesome, Thank you for the link

Does anyone know a resourceful website that explains HSPF and COP? Maybe AHRI has one?

Here is where I found the information source on HSPF including heat strips. http://energy.gov/energysaver/articles/air-source-heat-pumps .

If you read on down the page you will see their quote...

I have no idea how they calcuate heat strips into the factor lol I have been researching this on the net out of curiosity and cannot find anything that adequately explains HSPF

The HSPF even includes heat strips coming into play. But the thing I am wondering is how or what is really the difference in power consumption between a 7 HSPF and a 10 HSPF? like how much more...

Here's my understanding of SEER ratings. Lets say you have a 16 SEER Air conditioner for example,that would mean for every Watt of electricity consumed, the equipment would produce 16 BTU's. So to...

Sounds like you got it whipped.

If air handler is underneath the house, make sure the vents to the crawl space around home are closed off. The air handler is below the outside air dew point temperature.

short in condensing unit??? Nahhhh. probably bad TXV in air handler

Next time you are pumping down refrigerant open the high and low side gauges both. This will allow refrigerant to flow through your gauges if there is a restriction in your indoor metering device....

hmmmmm... next junk R-22 unit you have, dump some 404 in it and report your findings lol.

Hey guys I am looking for a form to write down all my data I collect from equipment (superheat, subcooling, static Pressure, temperature rise etc.....) I want them to be extensive in the amount of...

Turn your smart valve to "on" position

Have you considered consulting with your previous instructor?

Let me ask you this. What would happen if the contacts were normally closed when T-stat is off?

if indoor unit has TXV make sure it is opening when going into defrost. As you well know if your TXV is not opening during defrost the unit will not defrost properly. What kind of refrigerant? R-22

on the defrost board what is the timer set on? 30/60/90? sounds like your leaving your speedup pins shorted for to long since its kicking in and back out

55 degrees outdoor temp? there should not really be much of a need for unit to go into defrost. did u check charge? subcooling, superheat?
