Having problems with your Air Conditioners ?

Pressure, draft safeguard, or aux limit swtch did not close or re

\015 I have a carrier furnace. Pressure, draft safeguard, or aux limit switch did not close or reopened. This is what my furnace is blinking as a LED code. What should I do? My furnace does not turn on. The manual saysIf open longer than five minutes, inducer shuts off for 15 minutes before retry. Check for - Proper vent sizing and condensate pitch - vent restriction or hight winds - defective inducer motor or stat capacitor - defective prssure switch or connections. If it opens after trial for ignition period, blower will come on for 90 sec. recycle delay. - Inadequate Combusion air supply - low inducer voltage - disconnected or obstructed presure tubing. We had someone come out and replace an ignitor . The unit will come one once in awhile when the house is warmer. Sometimes the air is cool. Most of the time hot. The thermo is set at 71 but the house only reaches 61 - 63.\015

Answers :

The limit switch on the inducer has tripped. There are two wires that go to a small disk about the size of dime that has a small button in the center. Push this little button and you will feel a littl snap and the unit should fire up. Check all the manual reset limits as well. If the unit still won't start, jump the two wires by bypassing the limit switch. If it starts, then replace the switch. Bypassing the switch is only temporary and could lead to death if it is used as a permenant fix.

Janitrol (goodman) GMS9. Two years old. When thermostat is set low the ICM diagnostic LED is continuous on ("no signal from thermostat"), when thermostat is turned up then LED gives 3 flashes. Manual says that 3 flashes means "Pressure switch circuit not closed. Induced draft blower is operating", however the ID-Blower is NOT running. I ran a 110Volt wire directly to the ID-Blower to see if it runs independent of the control and it does run. I drew vacuum on both pressure switches and they do

The furnance runs fine for about 3min. Then the burners go out. The fan limit is still closed, pressure switch is pulled in, and the manuel reset switch on the flue is not tripped. What's causing the burners to shut down? Is there a factory problem with this furnance? Gas pressure is good.

I have a Fill-troll model 110 on a hot water boiler. The fill valve seems to allow too much water into the system (>30psi) unless I close the potable water supply valve. I have also observed that when I open the drain valve to release pressure on the system, the pressure drops as expected but after closing the drain valve, the pressure rises again even with the supply valve closed. I suspect that a restriction in the port to the diaphragm chamber is causing this behavior. Can such a

From your description it seems that the water in solenoid valve - fill valve is blocked open due to scale deposits. The solenoid valve can be disassembled and be cleaned; this is the only way to solve the problem. The flushing with vinegar c ... Air Conditioners

When I switch the T-stat to (fan on) the blower won't come on unless I move the Fan limit up close to the 100 degree mark and then I move that limit back down close to 130-135 degree and after approx. 10 seconds blower shuts off. I'm not sure where that fan limit is supposed to be set at, it was originally set around 130-135. It's a 2 wire limit and the range is 100-140. I know the stat is sending signal, I get 24v on green term. at fan center relay. Thanks, Dave

To help you we need more info. What thermostat and what furnace or air handler. There are two circuits involved. One is the green wire or g terminal that switches the fan relay into high speed for ac. The other is the w white that actuates the fan cy ... Air Conditioners

Combi boiler wont re-pressurize when i turn the little valve under boiler it just seems to run and run and the pressure gauge dosent go up at all? there are no leeks. but a minute a go it went right up to the red and wouldnt close then shut off,it restarted fine now it wont go up at all?

I have a Powermax 155 boiler that keeps losing pressure. Most of the time, I can usually work around this by closing the tap in the boiler until the pressure rises, but it's not working this time. I can't see any leaks anywhere and there is already an expansion vessel fitted - any ideas please?

1999 beetle AC... Ac works maybe 1 in 10 times for about 10 minutes then stops. Checked 134a level (good)... When AC is turned on, aux fan turns on, clutch engages on compressor and 134a pressure drops slightly, but not to normal operating range. When the few times it works, 134a pressure drops to normal range.

Modine HD100. After installation, on initial startup, green light on, amber light off. It ignited and burners came on, then went out within five seconds. Did this repeatedly.
