The Mosquito Magnet (MM**) has a tendency to stop working after a few seasons.

IMPORTANT: Do your work outside because it can get a bit messy and you will not want any insects,

which have not died, flying around in your house!

Most problems are usually caused by a failed (or loose connection of the) thermocouple or igniter. Another

common failure cause is a clogged filter!

All Mosquito Magnets have the following in common: Power supply [Cord or Battery], liquid propane connector

consisting of a regulator, a propane mixing chamber, Schrader valve, LP solenoid valve, LP sprayer, igniter,

thermocouple, catalytic converter, fan, combustion chamber and a circuit board.

When you power on the unit, it turns on the fan and delivers airflow through the combustion chamber. Shortly

afterwards, the igniter is energized [it gets hot & ignites the propane], then the solenoid valve opens and allows

Liquid Propane to enter the combustion chamber through the sprayer. As soon as there is combustion, the

thermocouple sends feedback to the circuit board and the unit will continue to run. If there is no combustion the

Thermocouple will cause a shutdown of the unit. The propane is then converted in to CO2 via the catalytic

converter before exiting through the Plume Tube. The Schrader valve is the access point where you connect a

CO2 cartridge Quick Clear [blow out foreign matter from the tip of the sprayer] the unit via CO2 cartridge.

For troubleshooting, you may need a multi-meter, Phillips head screwdriver, a few wrenches, high-temperature

silicone adhesive, a 12-volt AC power supply, and Teflon tape [I suggest using Yellow - double density Teflon

tape which is often labeled as "Gas type" OR RectorSeal #5 pipe thread sealant].

Before you dive in opening the combustion chamber try the following:

1. Disconnect the gas line from the propane tank.

2. Using the reset tool, reset BOTH the tank and the regulator. Do this procedure twice. For

pictures & detailed instructions go to:

3. Use the Quick-Clear procedure. For additional info & pictures go to:

http://support.mosquitomagnet.com/help/common/qcv.aspx

a. Use up to FOUR CO2 cartridges, in a row, to clean out the Schrader valve. This is very

important.

b. Do not do it just once or twice.

4. Reconnect the Regulator to the propane tank.....with the unit turned OFF.

Now...SLOOOOOOOOWLY, very slowly open the propane tank valve... To the 3/4 open

position. I cannot emphasize how important it is to open the valve slowly. Otherwise, you can

lock up the regulator.

5. Now turn on the unit and let it run for five minutes, then check to see if you still have a fault

code**. If you do, you will have to take the combustion chamber apart to repair it.

If this does not do the trick, try the following:

1. Disconnect the propane tank from the regulator and hook it up to your BBQ... Turn on the BBQ

and let it run for about 10 minutes... You could have air in the propane tank.

2. Reconnect the regulator to the tank with the unit off, then disconnect the regulator, then

reconnect it... Open the valve on the tank 3/4 of the way open. Now turn on your unit...

3. If this does not do the trick, disconnect the regulator from the propane tank and give it a shake…

If you hear rattling there is a very good possibility you have a bad regulator.

If the unit is up and running...always be sure to turn off the gas supply a minute or two before you turn

off the unit...Then run a Quick-Clear procedure... This should be done every time the propane tank is

changed.

What causes the problem? When liquid propane is pumped there is always a chance that oil from the

pump gets mixed in with the propane. It is the oil and/or dirt which plug the filter just behind the spray

head. [See Figure 6]
