HFH442 not heating after spark

I had my model #HFH442 running yesterday when I saw it spark inside - I immediately shut it off. When I turn it on now it doesn't feel warm - only a slight lukewarm feel on HIGH.

Re: HFH442 not heating after spark

There are four deep hidden screws on the back. more than likely they are phillips head type. a number 2 phillips will fit them. remove the screws and pull off the back. the element connections are push on spade connectors. see if one of your came off. just push it back on its terminal and it should work.

There is a thermal disc inside the heater that will tell the heater if it is getting too hot to shut down. When the disc cools off then the heater will start up again. After a wile the disc gets weak or it gets stuck open not allowing the heater to turn on. You will need to replace the disc or purchase a new heater as parts for those are not easy to find.

good luck

Had my kereosene 90,000 btu heater running yesterday and shut it off.plugged it in today and all it does is spit raw fuel out the front.i take the spark plug out and try to ground it i can't see any spark...


All the time.

You have a classic reddy heat problem. They use a system which sets the fuel pump pressure with bleed air. Comes out the back where there is a screw. If the pressure is not 4.5 psig the pump will pump too much or in your case too little fuel. This happens when the air filter plugs and changes the ratio. I have a tip at which explains the problem, how to fix it and where to get the parts at the best price.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

No flame

Several steps here to check...
turn power off unit and back on
set thermostat to heat
watch for pilot to ignite..igniter should glow orange or cherry red or spark if its a spark type ignitor
Did you see a pilot light ignite?

If not you probably have a bad igniter.

If pilot a little bit you hear a click of the gas valve opening..then the main burners will ignite

If you see the pilot and the main burner lights but goes out in a few minutes or immediately you may have an issue of the "high limit" switch tripping.

Is the blower fan turning that blows air out of your vents?
are all your vents open in your house? too many times i see homes with almost all vents shut.

My heat runs but the fan will not shut off unless I throw the breaker to shut off heat and fan. what do I do?

How old is the furnace? Depending on the control, the fan is turned on & off by a printed circuit board or a thermal mechanical switch that turns on the fan when the heat exchanger heats up. Either way it sounds like the control is sticking due to contacts that are inside the control being burned or pitted causing them to weld together when the fan is energized.

Installed Amana 12000 BTU wall pack type airconditioner yesterday. How do I get machine not to turn off and on during operation? Do I set it to run automatic? If I set it "cool" low stetting at 69 degrees,...

You definately want the compressor to shut on and off with the demand set by the thermostat. It is no different than a full size home split heating and cooling system. You set the thermostat for the temperature you want and then you let the system decide when to run the compressor

The unit will turn on and run fine for a few minutes then shut off. It won't immediately turn back on, almost as if it hans to cool back down first. Any ideas i have a lennox furnace

The ignitor will light, the blower will start up and run for a few minutes and then the system will shut down, and the blower will continue to run and cool down. The ignitor is not working properly, the ignitor has carbon build-up and need to be removed, cleaned all the black carbon from the ignitor with a little piece of sand paper and replaced, turn the heat back on and this should correct the problem.

Heater shuts down prematurly

If the heater runs fine for the 15 or so minutes without smoke/odor- do this
  1. check for water droplets on bottom of tank
  2. check for restricted fuel filter
  3. test photocell
  4. test safety control (reset)
You don't state whether this is a spark plug heater *or* Hot Surface Ignitor type. I made the assumption you were inquirung about a Spark Plug Heater. Disregard the list if the heater is an HSI type---- troubleshooting is different.

My Heater Sparks and shoots out smoke

Most likeley a bad transformer. Shut off the breaker, then remove the cover of the box containing the transformer & circuit board. If the transformer is bad, it will look and smell burnt. Mark the wires before you disconnect it, so you know how to connect the replacement. Then remove the bad transformer and bring it to a heating & AC parts store so they can match up a replacement part for you.

Inducer and ibm turns on and stays on no heat or cooling

Check to make sure you have 24-28 volts between R and C. If you do, you probably have a bad board but you also need to verify that you have the same voltage between W and C on a heat call if not then it could be something in the tstat ot he wires (jumping R and W pretty much rules this out).
The Kill switch may not reset the board, kill the power to the furnace itself.
Was the problem there before the new tstat was installed?
Also on some models continuous blower is initiated by a "kicked" roll out switch or and overtemp condition, Check for continuity on the whole safety circuit.
