Question about Grilling

1 Answer

I have a Heil N9MP2100F14C1 furnace running on propane that frequently locks out because 2 out of 4 burners will not light. The primary heat exchanger had a considerable amount of rust scale so I cleaned it hoping to improve my "draft" but it didn't help. The gas valve has been replaced and the pressures are correct so I'm stumped!

SOURCE: Ducane high efficiency propane furnace, pressure switch problem

A short cycle heat cycle indicat a pressure switch replacement was needed. This did not fix the problem. the problem was in PCV line since the end was filled with slugs and cause the line to backup with water. When this happen the system would stop asking for gas. the water would leak out and it would restart. The problem was fixed by cleaning value at end of PCV. This released the water, two quart of water, that was back up causing problem. Curious if a filter change indicator was providing a clue that was missed?

You have a dirty or bad heat sensor. When you remove the front panel on you furnace you will see a probe that is 2 or 3 inches long that is in the flame when the furnace fires up. If it doesn't detect a certain temperature within the first 30 or 40 seconds it shuts down the furnace. You can either clean the probe off with sandpaper, or purchase a new one. They aren't very expensive and are easy to replace. In my experience it is usually a build up of carbon on the sensor and a good cleaning with sandpaper and alcohol usually takes care of the problem.

My heil furnance comes on but no hot air or air at all


see this causes and fix it. God bless you
o light the pilot on a standing-pilot (always on) ignition system, follow the lighting instructions located near the control. Otherwise, try these steps: Light the pilot:
  1. gasfurnace1.jpg Press and hold the pilot control knob to start the pilot. Set the control knob to the pilot position. Hold a long match under the pilot gas port.
  2. Press the control knob; the pilot should light. Hold the control knob down until the flame is burning brightly (about 30 seconds). Release pressure on the knob, and turn it to the on position.
  3. If the pilot goes out when you release the control knob, try relighting, holding the control knob down longer. If the pilot again goes out, check the thermocouple (below).
Adjust the pilot:
  1. Remove any cap covering the pilot adjusting screw on a combination control.
  2. Turn the adjusting screw counterclockwise to increase the flame or clockwise to decrease it. It is correctly adjusted when the flame envelops the thermocouple bulb by 1/2 inch and appears dark blue with a small yellow tip.
Test and replace a thermocouple:
  1. Hold the control knob to pilot and light the pilot as above.
  2. Unscrew the thermocouple fitting with an open-ended wrench.
  3. Set a multimeter to the DVC (lowest voltage) scale.
  4. Clip one multimeter lead to the end of the thermocouple tube nearest the pilot and the other lead to the fitting on the other end of the tube.
  5. If the multimeter shows a reading besides zero, the thermocouple is functioning. Replace the thermocouple tube.
  6. If there is no reading, you will need to clean or replace the thermocouple following steps 7 through 11.
  7. Release the control knob and shut off the main gas valve on the gas-supply pipe that leads into the burner. Shut off power to the burner at the electrical service panel .
  8. Remove the thermocouple from its mounting bracket.
  9. Wipe the combination control clean and install a new thermocouple, tightening it by hand, then give it a one-quarter turn with a wrench.
  10. Insert the thermocouple into the pilot bracket, being careful to not crimp the tubing.
  11. Turn on power to the furnace and relight the pilot (above).
Adjust an adjustable burner air shutter:
  1. Set the thermostat to its highest setting to keep the burner running. Once the furnace has heated up, remove the burner access panel and loosen the locking screw.
  2. Open the shutter by turning it to the right until the blue base of the flame appears to lift slightly from the burner port surface. Then close the shutter until the flame reseats itself on the surface.
Clean removable burner tubes and ports:
  1. Shut off gas and power to the furnace.
  2. Unscrew or loosen and remove the tubes from the supporting bracket.
  3. Carefully clean the tubes with a brush or vacuum, making sure not to damage the burner ports.
  4. Use a stiff wire to clear any debris from clogged ports.

Hi, propane gas is really hard on a furnace in causing a burner or burners to carbon up. Yes, there is gas coming from this orifice, what you need to do is grasp the burner from the front, lift the rear out of the slot it sets in as you pull forward, and take the burner out. Turn it over and clean it out. It may be full off rust and some carbon. You can do this, as it may take care of the problem. We have taken on some furnaces, if your home is heating fine on the 3 burners, and remove the orifice and just plug it off. Doesn't hurt anything at all, I believe its a 1/8 or 1/4' pipe plug. I have done this many times when the temperature rise is to high on a new unit, and the only option is to shut down one burner. No harm or adjustments needed. Try cleaning the burner first and make sure the tail end sets back in its slot. If this works, great, if not, plug it off and your set. Will save on your gas bill also.

Intertherm propane furnace makes popping sound when running


It sounds like you have a possible hole in the heat exchanger. Turn the heat off and turn the fan on. If you feel any air coming back out of the heat exchanger, you have a hole. A yellow flame is not a good sign. I would even consider having a service professional come out and take a look.
