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.\015

Answers :

The limit switches are two wires that go to a small disk about the size of a dime. There should be a tiny button between the wires. Find all the limits and push them to reset them. The draft safeguard is the one that is located where the flu pipe leaves the unit. Sometimes the limits are stubborn and it's hard to push them in. If you can't get it reset then the limit will need to be replaced but it can be bypassed temporarily by jumping the two wire together. Do no do this as a permanent fix. It can cause death.

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

Pressure problems head pressure 250 psig and suction pressure is at 40. txv is opening and closing because i put the sensing bulb in hot and cold water and watched my gauges. Head pressure also is bouncing alittle bit. checked temps on either side of filter drier and they were only 2 degrees apart. so that tells me it's probably not plugged. I closed my liquid line service valve and ran the air conditioner to see if the compressor would **** it into a vacuum and it did. so that tells me that the

I have a GPG13 unit that is locking out on the aux limit switch. Can I increase the post timer for the bnlower. The blower compartment stays too hot after shut down and causes the aux limit to shut off.


You should be able to adjust the Blower off time by way of Dip switches on the circuit board...these are typically and band of tiny switches on a red block . Is the furnace new??? You may also increase the speed of the blower by using "High" speed wh ... Air Conditioners

I have 20 Siemens SKC electronic valve actuators which will not stop trying to drive closed after they reach the closed valve position. I have calibrated them multiple times, they are NO valves.

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. According to troubleshooting guide, if the amber light is not lit, trouble is flame signal below flame lost level. Now my green light blinks twice when I power it up. According to the error codes, pressure switch closed inducer off. I need to know how to correct both of these problems.
