How to change oven sensor

How do you know it is a sensor problem? If you know. usually there will be instructions with thepart. This part is the connection between the burner and power to the burner by way of the oven thermostat. It is not a sensor connected to the thermostat. The thermostat sensor is the long tube usually on the side of the oven. it has a small tube that connects to the oven thermostat. So if you have determined that the issue is the sensor or thermostat you will need a complete thermostat and the sensor I described. Some appliance parts dealers will help you if you have problems. I assume your existing part has burned and you get no voltage at the outlet? Usually the connection you cite is behind the plate holding the burner to the back of the oven. So you will need to remove the burner which will expose the connection the rest is just careful connection of wires usually by screws for the wires.

I am wiring a Honeywell wifi unit and I used a separate 24v transformer and connected to the c and rc terminal. My system is ac and heat and uses both and rc and rh wire. I wired the rc to the r ter

A thermostat is a switch. It connects 24vac from one terminal to another depending on the request. The 24vac comes from a transformer, usually located in the furnace and connects to the R terminal. Since you are using RH and RC without a jumper between it means there are two transformers, one in the furnace for heating (RH) and one in the air conditioner condenser used for cooling (RC).
Your old thermostat was probably mechanical and did not have a C (24vac common) terminal. Your new thermostat requires power to operate therefore needs a wire connected to a C terminal. I would get rid of the transformer you added and look for an unused wire in the bunch at the thermostat. If it's there connect it to C on the thermostat and to C on the furnace. Remove any jumper from R to RC or from RH to RC depending on your thermostat and connect wires same as the old thermostat.

How to replace spa thermostat?

You'll need to remove thermostat. Firstly disconnect the power from the spa. Behind or inside the control box/panel where the temperature dial is you'll find the body of the thermostat.
This body is usually attached with screws or a nut.
You'll need remove the wires connecting to the thermostat. Take note of their positions and which terminals they connect to.
Follow the capillary (copper tube) coming out the side of the thermostat to where the bulb is located. Remove the bulb carefully.
Once removed you should be able to find the model # of the thermostat on the body. Also pay attention to the diameter of the thermostat bulb and the length of the capillary. It will likely be an Invensys or Eaton thermostat, they are common and easy to find. Let me know if you need more help on this.

At the moment i am stayin in an apartment that needs a lot of work. the thermostat wasnt hooked up and was told the wires were there. i found wires and the old thermostat but there's only two wires. i...

On a 2 wire heating control, the 2 wires would be connected to the "R" and "W" terminals of the thermostat. The thermostat is simply a switch that routes power to the different connections inside it for different applications. Power comes in on "R" and is sent to "W" when there is a call for heat.

I need to replace my thermostat on my ge chest freezer model #fcm7sudww, I lost the wiring diagram and I need help to rewire. Thanks


Wiring diagram of the chest freezer turned into chest fridge. The junction box is not required if all connections are made inside the fridge service compartment. Active (A) connection passes via latching relay terminals
inside the thermostat.

Additional information can find HERE.

Hope helps; tell us news.

Hooking up the thermostat

Typically thermostats only have connections for two wires. All the switching and power control is done in the unit not the thermostat. A thermostat normally runs on low voltage, about 24 vac and only makes a connection for the rest of the unit. It also does not matter which wire you hook to which terminal. Let me know if you need more help.
