Gas convectors are very popular, as they are very reliable and practical to use, and their maintenance does not take much time and financial investment. Most breakdowns are thermostat or thermocouple failure. How to replace the thermostat, you will learn from our master class.
If the thermostat does not click when switching, if the convector turns on and heats up, but burns at maximum and does not respond to the turn of the temperature controller button, there is only one conclusion: the thermostat is faulty and needs to be replaced. Repair of the thermostat is impractical, and you can buy this part for the convector in any construction or specialized store.
Preparation for work
You will need the following tools to replace the thermostat:
- Phillips screwdriver;
- flat screwdriver;
- new thermostat;
- gas leak check brush.
Execution of works
We shut off the gas supply to the convector. Unscrew the fastening screw with a Phillips screwdriver, and remove the gas valve body.
This is how the upper part of the installed thermostat and the convector temperature control button looks like.
Use a flat screwdriver to unscrew the temperature controller button.
Unscrew the regulator bolt and take out the upper part of the thermostat.
The lower part of the thermostat (cone) is attached behind the convector body, we take it out.
We install a new thermostat in place. Top part first.
We tighten the regulator bolt, fastening the upper part of the thermostat to the stop, this will be the maximum temperature on the regulator button.
Insert the button and scroll it clockwise until it stops. We tighten the fastening bolt. We put the top cover of the button with the number 7 in the upper position.
We put the gas valve body in place and tighten the fastening screw. Insert the lower part of the thermostat (the bulb) into the mountings behind the convector.
We open the gas supply valve to the convector. To prevent gas leaks, it is necessary to check the joints of the gas hose with the pipe and the convector with a brush and soapy water. The absence of bubbles means tight connections.
We turn on the convector, turn the regulator button to maximum, then to a lower value, a click should occur and the main flame should go out. This means that the room temperature is higher than the value on the adjustment knob. The thermostat is working.
