I've got good flame replaced Powerpile pilot won&#t stay lit


The flame sensor is not producing enough volts to hold the gas valve open for the pilot light. Make sure the SIDE of the pilot flame is touching the sensor. If it in engulfed by the flame it won't work right.

I just had a new COZY L.P. GAS CDV336C installed... Every few minutes it makes a loud bang noise...It then makes pinging noises that gradually fade out...This happens 2-4 times every hour. The bang is loud...


Hi Loretta:
I'd contact the installer. This sounds as if there may be a slow leak. When the gas concentration is high enough it will ignite which would be the bang that you hear. The popping sound could be the flame at the leak source point re-igniting for a few times.
DEFINITELY CONTACT YOUR INSTALLER OR GAS INSPECTOR. THIS IS A SAFETY HAZARD.

WE HAVE A COZY GAS HEATER HAVE TRIED TO REPLACE THE THERMAL COUPLING AND THE HEATER LIGHTS AND SHUTS OFF AFTER FIRST CYCLE WHAT ELSE COULD IT BE IT HAS A HEAT SENSOR ON THE BACK COULD IT BE THAT


If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

My goodman furnace keeps lighting for about 10 seconds than goes out lots of clicking sounds


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad igniter what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat.
2. Draft inducer motor starts.
3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes.
4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas.
Solution: You probably need to purchase and install a new igniter. I would suggest that you inspect your igniter closely for cracks. Make sure you do not touch the igniter with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, roll-out switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Very loud wall heater (bang!!) heat up and cool down.


cozy heat exchangers do tend to make a lil more noise than avg. if its popping before the blower comes on its proubly the heat exchanger expanding. you would have to watch the exchanger while it was heating to see exactly what is causing the noise. but as a renter you should try reporting it to the landlord first and try to get a tech there before digging yourself

My Cozy Heater sized and installed by professional will not heat


I'm assuming your heater is the little Cozy direct vent wall furnace, your room calculations are correct, and at 57 degrees your main burner is constantly on. If so, it sounds as if you have too low a flame which can be caused by a main burner jet with an undersized orifice (like a propane one that got in the wrong assembly line) or obstructed by dirt, inadequate gas pressure, or a main gas valve that is not fully opening.

Open the pilot light inspection door and look at the main burner flame height. If it is less than 2 inches or so, check out the three possibilities above. If the flame is very yellow and wandering around lazily, check the air intake on your vent cap for obstruction.

Flame Adjustment


Make sure the unit is operating on the correct gas, Natural or Propane (LP). The sound you are experiencing is either not enough gas and the flame is burning inside the burner port(s) or too much gas and the flame is much larger than it has to be. At any rate, get a technician to check the gas pressure entering into the home. NOW!
