capacitor

  1. HVAC
    I noticed the fan was turning itself on and off every few seconds. Before I could turn off the system, it turned itself off for me (thermostat control display went dark and system was off, no breakers tripped). I did a search and saw mention of the capacitor being a culprit for the fan off/on...

    The other day I noticed that hot air was coming out of my vents when I had the A/C running. I went and looked at the condenser and the compressor was running but the fan was not and the fan motor was very hot. After doing some studying, I replace the cap and turned the A/C back on but the fan...

    I just replaced my condenser fan motor because the bearings were shot in my old one. My unit is a Keeprite KSSD 19-36, probably around 25 years old. The old motor had 4 wires, red, black, brown and white. The new motor's wires are yellow, black, brown, and brown/white. After I installed the...

    Hi everyone. I have a strange question that I was hoping for some opinions on. Three days ago, I had someone out to do a 30-point inspection on my furnace which was functioning properly. I was expecting a sales pitch and I have some experience with HVAC and a lot of experience with...

    Couple nights ago I noticed it was getting warm and muggy in the house. The a/c fan was running in the house, but the air coming out of the register wasn't cool. Went out to the yard and saw that the condenser fan wasn't running. Took the cover off and saw that the capacitor top was domed...

    I'm going to be in the vicinity of an electronic supply store this Friday/Saturday, what type of resistor should I get to discharge my capacitor on my blower motor to test it? If my capacitor is leaking I don't want to use a screwdriver and have it explode, that would be a sucky day. I've...

    A ceiling fan was running very slowly so I took it down and took it to be repaired. The capacitor was replaced (unfortunately I did not not the new capacitors rating) and the fan reinstated, only to find that it was running much faster than when it was running normally. After maybe 20 minutes...

    I need a little help. I have a RUUD Ultra Series. The compressor kicks on and then shuts down in just a couple of seconds. After it shuts downs, the fan spins. I've replaced both capacitors because the fan run capacitor looked bad on top. The ICC board is giving a error code of 5. I've...

    Hello, I have a Ceiling fan which doesn't run when turn on. Without the blades I can get it going after a little push. I suspected the capacitor, so tested the capacitor with a micrometer. It's a five wire CBB61 capacitor without the following: Gray-->Red should be 4uf------->micrometer...

    Everyone, I've tested everything I can test and even replaced the big capacitors on my HVAC unit outside to try and get it working; the problem is that once you turn the A/C on, or the temp inside reaches a point where the fan needs to kick-on, you have to go outside with a gun cleaning rod and...

    My Carrier AC stopped working several days ago. I could hear a light humming from the outside unite, but would not kick on. By the way, the last few years I have had to use a screwdriver to spin the blades to "kick start the season". That no longer works. So I replaced the capacitor and fan...

    I've been banging my head against a wall here for a few days, and I'm finally giving up and asking for help. My wife and I bought a fixer upper about two years ago that had been sitting empty. It had a 15 year old heat pump. Pretty much immediately I had to replace the capacitors and blower...

    Hi Everyone, After finding that my old dual capacitor had lost it's juice I made the decision to switch it to two single capacitors. The original was a 70/10 which is hard to find and shipping time was unacceptable. I purchased one 10 and one 70, came home and hooked them up according to the...

    Hello, I have a ceiling fan which runs for 7-8 hours everyday. Eventually, its capacitor perishes and it stops running, and i change a capacitor every 3-4 months or so. (Also i noticed with time, its speed starts to vary and decrease) i put a 2.0µF capacitor in it and in all my other fans as...

    Hi y'all. I was hoping for some input. Funny I have to deal with an a/c issue in November, but oh well. My A/C went out a month ago and through home tests, I determined it was the capacitor that needed replacement...the fan would buzz and only start when pushed with a stick. Sure enough, $12...

    Hey everyone, Just in time for a heat wave, our a/c went out today. When I went to turn it on for the evening before bed, it wouldn't start. The fan is not coming on at all. I looked at the fan outside, and it looks like the capacitor is old and rusted over. But, it doesn't sound like the...

    Hello, my condenser fan is not coming on and I cannot seem to find the same motor. The motor is a GE 5kcp39bg S457S. 1/10 hp, 208-230V, 1100RPM 60HZ. The capacitor does not have any numbers listed on it, but it has 3 posts coming out of the top. The unit is a Gibson GS3BA-024KA (2ton) I...

    Old capacitor was 45mfd and was replaced with a 40mfd. The unit runs now but will this still work long term? Why would the service provider use the 40 to begin with? Thanks!

    My HVAC stopped working all of a sudden. Its an R-22 System. The Suction line is warm(ambient temperature) and the liquid line is at the same temperature. The Low side as well as the high side pressure with the compressor off is about 150 psi(manufactured recommended Lo Side Pressure is 150 PSI...

    I have an older Heatwave electric furnace model no eld-85-45 Recently the furnace has been shutting off and not firing back up on it's own. If I turn the breaker off for a while then turn it back on, it fires up like normal but after a few hours it will shut off again. I have checked for frayed...
