May 02, 2009 · If that all check out. With furnace power shut off via the breaker, and pull the disconnect on for the out door unit. Remove the two low voltage wires from the contactor. Make sure they are isolated. The go back and turn the furnace back on. Call for cooling. If the fuse blows again your issue is with the stat wire (thats with it disconnected).
Changed clutch in Compressor and it will blow cold air for a couple of minutes then blow that 10 amp fuse in the fuse box. Changed A/C Compressor relay, same result. Put 15 amp fuse in, it lasted about a minute longer, then blew fuse again. Hoping and praying I do not have to change the compressor. Freon level good. Just keeps blowing that fuse.
Nov 26, 2019 · As you add up the electrical loads, keep in mind that a wire rated at 15 amps can carry 15 amps all day long. However, 15-amp breakers and fuses can only carry 12 amps—80 percent of their rating—on a continuous basis. Continuous basis is considered to be a circuit loaded to capacity for three hours or more. This 80 percent rule applies to all breakers and fuses. For more in-depth information on calculating loads, see Preventing Electrical Overloads.
May 25, 2011 · The furnace fan seemed to be blowing cold air. We turned off the breaker and this then turned off the fan when we did this last night. We then turned the breaker back on 15 minutes later and the fan didn’t turn on at that time, but just now, about 18 hrs later, the fan is blowing again.
Physically, yes you can.. Should you…? Was the right size fuse In there when it was to be replaced..? The trouble is that people will replace a fuse with anything that will fit in the fuse holder.. As far as safety goes, fuses are superior to circ...
Just depends what caused the fuse to blow in the first place. 25 amp may not be enough. Heck! 30 amp may not be enough if there is a fault in the system. It's highly unlikely you can harm anything with a lower amp fuse, but it may not last.
‘As a result of instituting a high rate of charge of the entire furnace burden and high blowing intensity in the oxygen blow of the bath, furnace productivity increased 2.5 times in 1966’ ‘This definition does not include any additional, or secondary, oxygen blows made after the primary blow.’

Two 15 amp breakers are fed from one 20 amp feed, the other two from theother 20 amp feed. These are the breakers that are used to replace the circuitson the main panel that are removed. Iremoved each 14/2 awg circuit wire from the main panel and pulled it out the back of themain panel.
