Hello, can anyone offer any advice on a three way switch? I am replacing a defective 3-way dimmer with a regular 3-way off/on switch. I put the hot wire on the black terminal and the two travelers on the opposite side on the brass terminals. The light comes on fine, but if I shut it off it...

yes, blower motor in furnace runs, but not condenser or fan outside. They both run in both units when pushing in the contactor. But I don't have 24 volts at the thermostat wires at the units but I do at the co Yes I have 240 v at both outside units. But no voltage (24) coming from the...

Hi, thanks for your reply. Yes, the units will run great while pushing in the contactor switch. But otherwise no. I disconnected the t-stat wires from the contactor leads at the unit and am getting zero voltage. Shouldn't I get 24v on the t stat wires when there is a call for cooling from...

fuses are also ok

thanks for the replies. I do have power to the units, breakers ok, thermostats ok. they both went out at once after cleaning. are there float switches on the outside units that may have tripped because of too much water when cleaning? if so, where are they located? thanks again

can anyone shed light on this problem? I just finished cleaning my two outside A/C units with cleaning spray from HD and a light rinse with garden hose. I disconnected the power prior to doing. Now the units will not come on...checked the circuit breakers, thermostats, etc and all is...

I have a quincy 325 that runs great and does not seem to be using or blowing oil, but recently I see oil dripping out of the big air and water filter when i open the stopcock to drain it. Could the oil I am using in my air tools somehow be gathering in the filter? Or could the intake air...

well, after a lot of head scratching and tracing electrical circuits, I found the issue....the exhaust pipe (PVC for 90% furnace) wasn't properly slanted (towards the furnace) because one of the plastic hangers which are nailed to the joists had broken and the pipe was slanting away from the...

Yes, I found that the draft inducer motor wasn't properly sealed to the back of the furnace and needed a new seal (which I made out of an old yoga mat) and reattached it with new sheet metal screws. Two different HVAC pros (?) looked at it and had no answer except to suggest a new furnace for...

Thanks to everyone who replied. Two HVAC techs looked at the furnace and scratched their heads. I found the problem myself! The draft inducer motor, although spinning good, wasn't firmly attached to the back of the furnace. When I took it off, I saw that the gasket had more or less...

Hi I had a new flame rod and put it in. The furnace is an old Rheem 90 plus it has the hot surface ignitor which is working normally, I put in a new circuit board and had no luck....still rapid clicking off and on, then goes dead after about 5-10 min of operation. I checked the two pressure...

thanks for the replies. I checked the pressure switches and they both close with a minimal **** on the hoses. The hoses are clear and it is easy to blow through.....don't think there is any blockage. New circuit board did not help the gas valve problem It is not getting a steady 24 volts...

Can anyone help with a furnace issue? Older Rheem 90 plus gas furnace. The blower motor was not coming on and the board was not sending a 120 volt signal after startup, flame was good, but no blower motor. But the blower motor worked fine when fed 120 volts. So I got a new board. Now the...

Is anyone familiar enough with flashback arrestors to answer a question? I got two sets at a garage sale and both look to be new, in original packaging. Both are Western Enterprises, one set is FA-10 torch style and the other is FAU-230 which appear to be regulator style. But I'm not getting...

ok, thanks for the reply..Lance

Can anyone give some advice on dimming LED lights? I just put in 10 in my kitchen, wife says they are too bright. The lights are controlled by 4 different switches...can I put in one dimmer or do I need to do all 4? How to wire in with hot, common, and neutral wire at existing switch(es)? Any...

Question...does anyone have experience with rebuilding/repairing the hydraulic unloader on the 325? Mine is stiff and the plunger won't move in and out freely. So I am not getting any "unloading" when the compressor shuts off. I thought about soaking the unit in carb cleaner or other solvent...

I think I may have that backwards. Shouldn't there be air pressure on the diaphragms only when the compressor is not running and there is pressure in the tank? Then when it starts and oil pressure is up to 15 or whatever, the hydraulic unloader should shut off air delivery to the diaphragms...

Many thanks to C96 and everyone else who replied...the compressor is running great. It is a Quincy 325 circa 1968 that I hauled out of a junkyard and rebuilt. It holds a steady 20 lbs oil pressure and pumps air from 0 to 180 psi in about six minutes. But when it stops there is no unloading...

Here are some better pics of the box. Since these were taken I did move the third wire for the 220 circuit (white wire, third from the top, right side) to the ground bar as suggested. But the ground bar and the neutral bar have continuity so I don't know whether this matters or not, the box...
