Having problems with your Air Conditioners ?

Furnace ignition York P2DP10N gas furnace - when its called to heat some times ingnition sequence is normal. Other times its haulted after 20 seconds and the sequence is restarted. Some times this happens 2-3 times before the burner gas valve is openind. There is nothing wrong with the hot surface, the sequence is not allowed to get to the stage when its stopped.

Answers :

The probable cause is the pressure switch. It's a round disk either silver or black in color. They can stick in either the closed position or the open position depending on what your unit needs to fire. You can take the rubber hose off from the inducer motor and blow lightly and **** in lightly to make sure the switch is free from debris. Then try again and if it continues, then you will need to replace the switch. It can also be a limit switch that is going bad as well.

I have a goodman furnace model gmpn 080-4 92% 1997 Gas vave would not open after igniter came on. the voltage was 15 prior to sequence and 26 upon time for gas valve to come on. I ran a jumper from trans to gas valve and it opened. I replaced board. it functions properly now, but I still have 15 volts at gas valve when it is not calling for it to open. Is this normal? If not what could cause this?

General rule is 24 volts to operate control valve. check common at valve to white at valve or out of board. 24 in call, less than 24 when off. sometime s these things back feed or give a false reading. voltage can read say 15 volts but under a load i ... Goodman Air Conditioners

I have a problem with my Johnstone furnace "Mod.# MBA 040 nh2r" every time the furnace calls for heat the gas valve release the gas a few seconds before the igniter witch causes a small explosion. This happens after the firt initial start and continues every few seconds.Also I can't seem to find this brand of furnace.

Hi, this is called delayed ignition which raw gas is let into the combustion chamber and ignited a little to late. which causes this explosion. I have had my eye brows and eye lashes burned completely off do to this. Johnstone is a very popular brand ... Air Conditioners

Rheem-Gas Furnace I have a gas furnace that will not ignite. I have attempted many times to start/ignite it using the manual suggested sequence, and I have been unsucessful. In diagnosing the problem(s) the technicial manual flowchart suggests that I replace the vent pressure switch. How do I not know I need to replace the igniter. What tests can I do to ensure it is.If I let a proffessional trained technician perform the work, How much should I expect to spend?

It may be a little difficult to diagnose if you don't have a volt/ohm meter to check the switches with, but I will try to help what I can.\015\012\015\012The first thing to check is the pressure hose from the vent fan to the pressure swit ... Air Conditioners

I have two heatpumps up and downstairs and two furnaces (piigy back). At times my pump outside freezes up and cold air blows in the house.

I have a 2 year old Goodman GDS80703ANA furnace that has always had a problem starting. Sometimes it starts on the first attempt but other times it takes 2 or 3 attempts. This is what I see happening: The Induced Draft Blower starts and runs- the Igniter will glow for a few seconds and just as the igniter starts to stop glowing I hear the Gas Valve click and open but it is too late. On the next attempt or so, the Gas Valve will open sooner and burner will ignite. My question is: Is the Integrate

A 2 month old Goodman GMH95 natural gas furnace has been working properly until tonight. Now it starts up properly, but after 30 seconds (and right when the cirulator fan kicks on) it shuts the gas valve stopping the flame. LED light flashes 8 times, which is not an option on the trouble shooting guide. Unit will retry every few minutes and cycles this way over and over. It appears the control module is not receiving the gas flame detection signal. What do we need to do?

Goodman's control boards are very sensitive as well as the connections to the gas valves. Check the wires and make sure they are snug and tight. With it being only 2 months old, I doubt the board is bad or the flame sensor(unless it is a used syste ... Air Conditioners

I have a mobile home furnace Intertherm #1378. The pilot light is on, but the burner will not light. The thermostat clicks on and everything seems to be running properly, but there is no flame.

Confirmed gas valve is functional by switching out valves. Check all wire connections. Could it be the remote sensor or another 24 volt sensor at the IFC that is locking out the gas valve?

There should be a flame rod that senses the flame , if not will shut off gas valve. It is a stainless steel rod that is in the flame path and wires into the panel ground. You might try to clean it with some steel wool or fine paper. Sometimes they wi ... Ruud UAKA030 Air Conditioner

If this happens each time the blower starts, you have a crack in the heat exchanger and need to replace furnace. If the blower is not starting, it could be a high limit opening up because of the heat being generated. By pass the high limit circuit to ... Air Conditioners
