Ir tourch has brocken off the unit - Yukon (744105200223) Weapon Sight

In back bottom right on the HT-R640

nitevision is in monochrome.. but if the irs dont work in that camera need to either get an ir light for that unit or replace that specific camera..the ir board is burnt out..or disconnected..I have several systems in use at different locations and I do installs for residential locations..I get some of my units off ebay..

You need to use silver brazing flux after you thoroughly clean the connections and for sure no oil creeping into the area where you are brazing hope this helps good luck.

the thermocouple that senses the flame is defective and won't keep the gas valve open to operate the unit,ace hardware carries most thermocouples,check them out,just get the right size that goes into the gas valve and make sure the sensing bulb is positioned within the flame for proper operation

first check the lock lever green maybe if you pull up that lever to lock the metal who hit in the middle of the sensor is not hit by that metal or check the harness or wiring in front of unit 1 maybe the wire is loose connection if the same after you check those check the connector at the rear side of unit 1 maybe the gold pin connector is mis align

cartridge, the toner in the supply route between the toner cartridge and the
hopper may leak between the gap between the toner cartridge case and the holder of the machine.
<Factory Measures>
The gap between the toner cartridge case and the holder of the machine is covered with the plastic sheet and the shape
of the front unit cable guide on the toner sensor is changed to prevent the toner from flowing onto the toner sensor.
P-1 Position where the toner cartridge is installed
nside and replace the front unit cable guide into its new type.
Points to Note About Service Work:
When the front unit cable guide is replaced, implement periodic cleaning (every year) for the area around the photo
sensor (PS3/PS4/PS5/PS6).
For the affected machines or later, implement periodic cleaning (every two years) for the area around the photo
sensor (PS3/PS4/PS5/PS6) and the area of toner leak [1].
Service Parts:
Supply of the new part(s) will follow a normal supply pattern.

if you have to tap the tourch to get it to work then something in the tourch is loose or worn,have you tried to replace all the consumables in torch,check that all leads are tight.as far as parts go to your local welding store(praxair,midwest air gas, s j smith)not a hardware store,

You still have shorted out components on the circuit board, you will need to download tha service manul here to do an indepth troubleshooting: http://elektrotanya.com/

it could be the compressor

We don't recommend removing the door or hinges unless it's absolutely needed, because failure to get it perfectly aligned can allow leakage.

Doors can be separated while still attached, to replace only the needed part(s). The drawing below shows an example.

You can find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

If you do need to take the door off, it may be easier to take the oven down from the wall. For safety's sake, that should be a two-person job and it's really helpful if you have your original installation instructions to do this:

If you need more help, we recommend that you either buy the service manual or contact a local GE servicer.
