The problem is your gettign a code and the legend is telling you its the pressure switch? From your description.

Well it is going to be rather difficult for you to check the switch without a .10" gauged water manometer gauge. It would be easier and cheaper for you to purchase another switch but if its only 2 years old the factory warranty is usually 5 years on parts. All you'd owe for is labor and freight if you have to have it sent to you. Take your model and seril no and go to who you purchased iot from and tell them what code your getting.

Some of these pressure switches and the boards that control them look for the switch to acuate both ways on and off knowing that the switch is actually working and not stuck. So you could start out by jumping the correct NC normally closed circut turn on the furnace and remove this jumper and then close the NO normally closed circut with a jumper. This isnt a fix but may help you see if the switch is actually at fault. If you get it to lite off let it cycle back off and note if it works all way through the cycle. If it does Your problem is most likely the switch because you just did all it does only by hand. DO not leave it this way because you can cause a more seveer problem and it is can develope dangerious consequences. This is just 1 way to check the switch. Another way is to check it electrically. If your femilur with open and closed circuts check across the closed and open circut whith it off then with it running and (if it has 3 terminals wires in, if it just has 2 wired in then it is not going to look for one of the operations Ive discribed). And then check and see if the voltages reverse while beginnign to lite off. If it does reverse Im betting you have a different problem and the swich is what the board has been told is giving the trouble.

Hope this is clear. If not get back to me. If it helps please grade me accordingly. THANK you and GOOD LUCK

I have a Rheem Classic Super Quiet 80 gas furnace (for heat). The fan stops when the "heat" turns on.


Any time I ever had trouble,first thing to suspect is the thermostat.
They lose contact sometimes and sometimes you tap the face and they work til next glitch.
If the thermostat has some years on it,go ahead and replace it.
Can't you just leave the heat and fan in auto? That would be best,I think. don-ohio

Rinnai ex 38 flashing code 99. I took the vent apart and there is no blockage. Unit has only been installed one month.


If it is only one month old doesn't do anything but call for warranty serving. ANY attempt to repair this will void the warranty.

Why does my home A/C unit result in a constant stream of water coming out of the overflow drain? I've had the same unit for 5 years, and it seems that it drains water in ever-increasing amounts. Als


Sounds like it is freezing up. Kind of hard to say since you did not say whether it is a central heat and air system. My overflow was constantly draining onto my patio from overflow. I crawled up in the attic and followed the pvc pipe where it came in from the outside and closer to the central unit in the attic I drilled a hole in the 90 degree elbow of the pvc and unclogged the pipe which was frozen from running so long. Then I covered the hole with silicone. no more leak coming from overflow

Electric Furnace stopped running


You have one of two problems. Either the capacitor for the motor has failed or the motor has failed. I would turn off the power to the unit and see if you can locate the capacitor and remove it. An ac supply or electrical supply house can match up the capacitor. This is relatively inexpensive. Otherwise you will need a new motor.

Is it cost effective to replace draft inducer blower on 22 year old furnace?


Depends on the cost to repair. Probably a 22 year old furnace is not very efficient also. Take every thing into consideration.
If it still works it may work for a while but you don't want a break down in the middle of winter.

Household steamer not heating at all


Well, first thing, just hook up service water and turn it on so the water heats up. Leave it long enough for water to get hot. If water doesn't get hot like should, then heating unit is malfunctioning. If it is getting hot after a while, you pull the handle trigger and water comes out, you have to wait long enough for the hot water to get to the head/trigger for it to go into the nozzles. If it was working ok before, and you were waiting for the water to heat, then then it should be working fine. Tell me what is happening if you wait for water to heat and get to the nozzles. I'm right here at my computer and we can get this thing going if the heater unit is good. Regards, Rigger.

Why can't I lower my honeywell 8500 below 67 on cool?


With a two story house you have to be aware that cold air flows downwards so any cold air coming from an ac unit will flow downstairs( normally down the stairway) so unless you can close off the down stairs then the up stairs unit will be cooling downstairs as well. Ac units have a thermostat located in the air intake and it cools until the cold air has risen to that point. In effect the space above the ac unit will be hotter than the floor. Knowing how they work ,you can see that the upstairs unit will never reach the set temperature because the cold air is continually heating from the house and will never get to the top thermostat.
So your solutions are
1-- fit controls that restrict the cold air from leaving the upper floor (Doors)
2--don't run the upper ac unit unless you are living up there (waste of money
)3 place an ac in each upper room and keep the room door closed
