Monitor and Toyo are basically the same. They both use a solenoid type fuel pump. The pump can be taken apart but you will NEVER get it back to working condition, so don't open it up. Clean off the stainless steel mesh screen with gumout - works best. The solenoid pump operates off a relay on the computer board and the pump's controller that provided pulsing to the solenoid. Remove the copper pump tube off the pot ONLY when it's cool or slightly warm. The bulkhead fitting is brass, but the gland nut on the tube is steel and they expand at different rates.

A Monitor 41 could be 20 years old now. When you say the iginter works does that mean the burner heats up around the igniter? If it does then the igniter is probably OK. Now for the pump. Is it cold or snowy where you live? If so, you should check the exhaust pipe to make sure it does not have ice or frost on it. Either will cause the fuel pump not to come on. Monitors are a little tricky to work on if you are not sure whats up. Be very careful removing the fuel nozzle to check for fuel flow. Don't remove it if it is hot, you run the risk of twisting it off the pot. If you are not handy with all things mechinical I would look for a dealer to help you out.

I'm not real familiar with Monitor heaters, but if they are like Toyos, you may need to replace the pump.

I am working on a monitor 2400. heater will run normal until it reaches set temp. when it goes to mid burn the flame goes out and code 14.


E14 Flame failure: There are obstacles at circulation air inlet or outlet. Fan cage is clogged with dust. Gas pressure dropped when other gas appliances are turned on. (this may also apply to K1 fueled units if you have another K1 based heater)

Here are the rest of the fault codes I found:

Digital Display Reason of indication Trouble Point
E01 At pre-purge, flame rod is sensing flame when there should be none. Flame sensing circuit, grounded flame rod or pinched wire. E05 After power on, power supply to the microprocessor timing circuit is incorrect. Timer clock circuit bad or power cycles (hertz) to unit above or below acceptable levels.
E06 A starting of operation, the circuit to drive photo triac of solenoid pump is malfunctioning. Solenoid pump control circuit has a malfunction.
E08 Revolutions per minute of combustion blower are malfunctioning. Combustion blower or combustion blower control circuit has a malfunction.
E13 No ignition. Failure of ignitor, solenoid pump or circuit board. Incorrect wiring or flame rod touches to burner parts. Air pressure switch or overheat open.
E15 Power supply voltage too low. Voltage too low or power detector circuit has a malfunction.
E16 Load failure of combustion blower motor Flue pipe is restricting air flow.

Oven wontr come on, but broiler does//


you have a bad ignitor part number 74007498 and it's around 65 dollars.pull out the racks and remove the floor of the stove and you'll see the ignitor screwed to the burner tube,wet the screws with a wet paper towel,they will come out easier or if it makes it any easier remove the tube and then remove the ignitor.first start the stove if the ignitor glows but doesn't ignite the flame in 40 seconds or less it's bad,if it doesn't glow at all check it for continuity but it sounds like the ignitor is bad,if the new ignitor comes with wire nuts,cut the wires close to the body of the old ignitor,trim some of the wires back on the new ignitor and wire nut them together with the ceramic wire nuts,on some you can get the screws out of the ignitor,cut the wires close to the body,mount the new ignitor,trim back the wires on the new ignitor and wire nut them together and you're done,it doesn't matter how long the wires are just as long as the wire nuts are under the floor and away from the tube.it might help to remove the bottom draw to get at the wires,hope this helps and good luck.

Furnace kicks on but the gas stays on for about 6 seconds and then shuts off and repeats this two more times and then stays off for 20 minutes and then starts all over again


This tells me that its either an ignitor or flame sensor. You will need to check to see if the ignitor is working by watching it when the unit comes on and if its not then replace the control board for the ignitor or the ignitor itself. If it is coming on then its the flame sensor. Sounds like the ignitor though. I would check that. These go back on a reg. basis.
Feedback is apprec. Thanks.

I have a miller furnace in my shop, runs on K1, recently I ran it out of K1,after putting 100 gallons in the tank, I cannot bleed the system, furnace will start, nothing comes out of the bleeder valve.HELP


Check the filter on the tank to make sure it is not clogged. Then iff it still will not bleed take the screw out od the top of the pump usually a 1/2 inch or 9/16 and fill the pump with kerosene and then put the screw pack inand try to bleed. sometimes priming the pump will get the pump running again because it air locks the when it is run out of fuel.

The ignitor in our oven is no longer being made the replacement is a robertshaw 41-208 how do i put a square peg in a round hole


There should be a bracket with the new ignitor. There are also universal ignitors of the same type as the old one that can be made to work.

All Pro 200t Will not ignite


John- the ignitor does not stay on for the duration of the running time. It only stays on for the first 5 seconds. This is long enough for the flame to ignite and perpetuate itself, assuming the fuel delivery system is up-to-par. The photocell monitors the flame color and if the flame becomes off-color then the photocell tells the control board to shut the unit down. Naturally, too rich or too lean affects flame color.

Now, I'm confused by your description "the heater cycles 3 times". Tell me more.

I'm glad to see that you checked the pump pressure. Have you used soapy water to check for air leaks all the way to the nozzle? A leak in the airline, fuel line, or a crack in the nozzle adapter will cause no fuel delivery, or reduced fuel delivery as well as reduced atomization of the fuel - all of which can cause a lack of combustion. A restricted fuel filter will cause starvation.

Eliminate all possibilities of a fuel delivery problem before you start blaming electronics because there is not much way to test the board or the photocell successfully without DESA's diagnostic tool. Unfortunately, replacement of the componants is cheaper than the tool.
