Montgomery ward oil furnace

I have an old montgomery ward oil furnace that i am trying to clean. the unit works great-no problems. i removed and cleaned the flue pipe which was half full of soot, scale, and rust.then i started cleaning the furnace. between where the flue pipe exits and the big round metal drum(heat exchanger or fire box?)there is about a 2 inch space that is full of scale and debris. icleaned as much as i could, but there is still more that is really hard to reach.i found traces of insulation and stopped. what i would like to know is; is this area supposed to have insulation? how critical is it that i remove all of the scale? and can i pull the front panel off that is above the burner to gain access for cleaning? the model # is 15AN-6124A if that helps you any. i appreciate any help you could give

Use a flexable wand and get as much debris as you can. I would not be too concerned with the insulation unless you see that it looks burnt. Open as many ports you can find and clean where you can. I sometimes inject air from an air compressor at the same time. It makes a mess but gets things moving.

I have an oil fired aga the oil will not come throw to the burner


see the following steps:
f the burner doesn't run, set the thermostat a few degrees higher than normal to see if it comes on. If it still doesn't come on, check switches, and breakers and fuses (see the Electrical Service Panel Fix-It Guide). If the unit has a reset button, press it. Also oil the motor at any oil ports (see below). If the unit doesn't want to start and run, first check the c to make sure that the ignition is getting power. If there is power, check the built-in safety controls (see below) that may turn the system off if they perceive problems.
If the burner cycles too often, replace the filter (see below). Also, oil and adjust the blower (see the Forced-Air Distribution Fix-It Guide).
If the burner runs but won't fire, make sure the oil valves are open and that there's oil in the tank. Check the tank level with a clean stick.
If the burner smokes or squeals, shut off the unit, let it cool, and fill the oil cups. Recheck them after the motor has run for an hour.
If the chimney smokes even after the flue has warmed up, the unit is wasting fuel; call for professional repair.
Safety Controls
Oil furnaces and other heat systems include safety devices that monitor operation and turn off the unit if something goes wrong. In some cases, the safety device can be the problem.
If you encounter an operating problem with an oil furnace, first reset the safety and try again.
If the burner kicks off again, shut off all power at the electrical service panel ; the burner motor and ignition may be protected by separate fuses or breakers.
If the sensor has a photocell, wipe it with a clean rag or tissue and see if the furnace starts.
If the safety is a stack switch mounted on the flue, remove the screw holding the unit to the stack, slide it out, and wipe off the sensor.
If the furnace won't start after three tries, seek professional assistance. Unburned oil can accumulate in the combustion chamber and "flash back."

I have a very old floor funace. Peobably around 45 years old. There's know fan, just induction gas heat chambers with a grate on top. The unit stopped working when the HVAC guy changed the Thermostat...


He needs to put the old stat back on...... The old stat is a Millvolt stat and the new Digital ones won't work. And I don't know if they make a digital for Millvolt.... The old floor furnaces used a power pile like a oversize thermocouple for the power to operate the gas valve.

My Montgomery Wards big floor type demumidifier


If your dehumidifier doesn't seem to run often but the humidity in the room is high, try adjusting the humidistat control on the dehumidifier to a dryer setting. If the dehumidifier seems to run constantly, but there's little or no water in the container, there may be a problem in the refrigeration system. Try cleaning the unit. If that doesn't work, you can't repair the refrigeration system yourself, you need a qualified appliance repair technician to do that.

You need a very kong wire and a kitchen match. Turn the knob on top to pilot and push down have your flame already down thru the pilot hole at the bottom of the inside of furnace.

GDS80904BNA Goodman furnace only cylces off for a minute


Sounds like your repair man ripped you off. He should have stood behind his work.
1. I would try to clean the flame sensor located just below the burners. It is connected to "one" wire (Not the two wire) clean rod with sandpaper.
2. The old and thermostat could have a had a bad heat anticipator. if the new t/stat is not digital the heat anticpator on the T/stat needs to be adjusted. slide the small adjuster arm under the cover to about .6 or .7 and see if the solves the problem. if the t/stat is digital it should be preset from the factory.
3. last resort have a service man check your pressure swith. could be a slow inducer motor, blocked or bad vacum line, or a restricted drain or flue pipe.
Good luck!
