Aboutjohn t. borgman Expertise I work days, so I can only answer early in the day or later in the evening, I live in Oregon. I have been so good at all the other area's of hvac, I am probably the only hvac guy that does not know oil. ( lol ) I am very well versed in gas, electric and heat pumps and will only answer residential applications. I have been known the past decade or so, by my employers as the guy you send when no one can figure it out. Trouble shooting is my special. I understand the physics behind air flow, refrigerants and electricity. I understand programmable t-stats, zone controls, economizers, fossil fuel kits and the engineering thought process in the wiring and construction of residential equipment
Experience I was lucky enough to start in this field over 25 years ago as an installer, for a company that installed the best duct systems I have ever seen, even to this day. The best ,as far as understanding the way air really flows through a duct system, from the return air to the very last supply register . They also had great pride and the duct work was put in, not only to last 50 years, but to look exceptional. Then as I started doing service work, I was again fortunate that I found a 3 year engineering class being put on be a man that was the educational director for the Entire united states for a society called " the Refrigeration Service Engineering Society " And for the next 3 years I schooled at night and practiced what I learned during the day, a great advantage over schooling and then trying to remember it years later.. Versed in duct design manual J heat gain/loss calculations. Also experience in wine rooms and indoor swimming pool hvac & humidity controls
Publications I have 2 inventions that have gone through the process and been recorded at the National Institute of Standards and Technology from start to finish and thus been invited to national innovation workshops by the dept. of Commerce and the dept. of Energy. They are waste heat recovery devices that N.I.S.T approved as valid and am currently looking for marketing partners to get this product into the hands of consumers and make a BIG difference in Energy savings for every Household and Eatery and take a big bite in the the peak hours power consumption that face our Utilities companies.
Education/Credentials factory training in Lennox ,Rheem, Ruud ,Trane, Tempstar ,Carrier, Day&Night, Payne, Bryant, Coleman, Intertherm, Ultra boilers, Unico, Mitsubishi,Sanyo, Taylor, Nicewonger, . Associates degree in Refrigeration Engineering. Certified with Energy Department, Check-me Program, have N.A.T.E. certifications in gas, a/c & heat pump. Teach and apprentice at every company I work at.
Question I HAVE A RUUD 96% FURNACE, I JUST IN STALLED IT AND WHEN THE
SAFTY SWITCH IS PRESSED THE POWER LIGHT COME ON AND THE FUSE
PLOWERS. I HAVE INSTALLED FOUR OF THE SAME KIND WITH NO BROBLE
Answer Cliff,
You have a low voltage ground somewhere. First thing to do if your not real good with a volt meter is to unhook all low voltage wires from the board and try one more fuse. If it blows, then it is a factory miss wiring and you will have to do some searching inside the unit. If it does not blow then you have a control wire grounded or miss wired.
Another way is to remove the fuse , tape the safety switch closed and check with your voltmeter with the control wiring removed for something less than 20 volts, like 10 or 15. Do this quickly, because if there is a problem, you do not want to take out the transformer.
Next if furnace is ok, remove the tstat and seperate all the wires and the same at the furnace and do a continuity check between all wires looking for a path for electricity. Same with outdoor unit.
Of course the first thing to do is double check your wiring, even a seasoned veteran can make a boo boo
