5 Reasons Why Monitor 441 Won’t Ignite [Easy Solutions]

You can easily deal with the reasons why your Monitor 441 won’t ignite. Just maintain the following instructions, and everything should be okay.

Reason 1: Power Connection Failure

Monitor 441 heater runs on electricity. If the electrical connection is not secured, then the whole system will obviously collapse. The ignitor will not escape its effect. I am trying to say that if the heater loses connection with power, the ignitor will stop working.


The solution to this problem is very simple. Just secure the connection, and you are good. However, there are a few things you must do to ensure a perfect connection. Here they are:

  • See if the plug is properly inserted into the outlet
  • Make sure that the outlet is supplying electricity (use a tester for this purpose)
  • Look for damages in the wire connection (replace the wire if it’s damaged)
  • If everything seems okay, the problem is with the heater receptor. Call an electrician to fix it
  • See if the fuse of the heater is okay. Replace it if needed

If the power connection was the issue, then your Monitor 441 should now ignite again.

Reason 2: Empty Fuel Tank 

Just so you know, Monitor 441 uses 0.3 gallons of kerosene oil per hour. And because Monitor 441 is so fuel-efficient, it is easy to forget when the fuel tank becomes empty. Once all the fuels are drained, there definitely won’t be any noticeable ignition. 

You can be sure that this is the case by checking the fuel tank when you notice no ignition on Monitor 441 or notice the burner status flashing on your MPI monitor.


You can solve this issue just by pouring more fuel into your Monitor 441 fuel tank. Here’s how to do it:

  • Turn off the whole heater system
  • Take a universal fuel pump
  • Install the hose leading to the Monitor 441 fuel tank on one end
  • Attach the other hose to the fuel cylinder
  • Once the installing process is done, start the monitor and let it do its work

Your Monitor 441 fuel tank should be full within 10 minutes if you have followed each and every steps accordingly.

Reason 3:  Contaminated Fuel

As you already know, a heater runs on oil. But if this oil somehow mixes with water, then the fuel may lose its functionality. And when this happens, the ignitor will stop functioning as well, and you will notice your MPI monitor shuts off frequently or won’t ignite.


The solution to this problem is replacing the contaminated fuel. You can pour in a new batch of oil in the same way mentioned in the previous point. But how do you drain the old oil? Here’s how:

  • Turn off the heater by unplugging it
  • Drain all the contaminated fuel as mentioned in the previous method
  • Get a siphon fuel pump
  • Set its lever-end’s hose in the fuel tank
  • Put the other hose in a bucket
  • Start to pump at a light pace
  • Increase the speed gradually

You have to keep doing this till all the oils are drained. And right after that, you have to refill the fuel tank. 

Reason 4: Clogged Fuel Filter 

A clogged fuel filter prevents the proper flow of oil. As the result, the heater doesn’t get enough power to run the ignitor. Sometimes, though it ignites, the burner shuts off a few moments later.


There are two things you can do in this situation. I will walk you through both here. Firstly, you can clean the fuel filter. Here’s how to do it:

  • Disconnect the power connection from the heater
  • Turn off the fuel flow at the oil barrel. (place oil rags here)
  • Locate the filter at the right-bottom side of the inside of the heater
  • Unscrew the 2 bolts holding the fuel filter there
  • Remove the fuel filter from its place
  • Now clean the filter using carburetor cleaner 

Once you have cleaned the filter, you have to place it back in its place and screw it up. However, if the fule filter is too old or too much clogged, you have to replace it. In this case, you have to install a new fuel filter. Remove the fuel filter in the method mentioned above, and put a new one in its place.   

Reason 5: Auto Timer 

Your Monitor 441 will not ignite with the operation switch if the auto timer is on.


Just reset the auto timer and you are good to go. It is nothing difficult to do. Simply press the auto button one time and everything should be okay.

Once you have dealt with all these points, your Monitor 441 heater should ignite properly.

MPI Monitor 441 Keeps Shutting Off [How To Fix]

MPI monitor heater runs with ignition. Once the ignition starts, the whole system begins its functionality as well. So it means if the MPI monitor keeps shutting off, the culprit here is the ignitor. If the ignitor was not faulty, the MPI monitor 441 wouldn’t have shut off.

You can solve this issue by the methods discussed above. But the problem can still remain. In that case, you have to replace the ignitor. Here’s how to replace MPI monitor 441 ignitors easily:

  • Open the side panel of the heater by unscrewing the bolts holding it there.
  • Locate the ignitor situated inside of the burn pot
  • Unscrew and remove any kind of obstructions holding it there
  • Pull it out of there and disconnect the wires
  • Install a new ignitor by setting up the wires and installing it in its place

Once you have perfectly installed a new ignitor, all the issues you have faced so far will be solved. And your MPI monitor 441 will stop shutting off.
