Turn the thermostat mode to off. Push & hold both temperature up &down at the same time and screen on tstat should change and display Unit this is where you change C to F setting. I dont quite remember how to exit, if you change your setting and leave tstat alone and it should change automatically Good luck

John deere 4310 temperature gauage not working

Thermostat in 4310 did nt help

I don't know about next move, but my first move would have been to check and clean the connection to the temp. sensor and ground.

We have had several machines do this, sometimes going up dramatically in temp. readings.

It turned out each time to be a change in resistance in the circuit. The temp. sensor changes resistance as it warms and cools, this means that when the circuit gets some corrosion or dirt in there the temp. reading changes too.

Why does wine freeze?

Check for corrosion on the temp probe. The digital displays use thermistors to determine the temp so if the probe has dust on it it will change the resistance reading and tell the cooler that it is warmer than it is. All you can do is clean the probe, and if that doesn't solve the problem then the control or probe are faulty as they are usually one piece you will have to change it out. If you are mechanically inclined you can change out the temp control with an a19 abc24c remote bulb temp control from Johnson controls and that will last of the rest of your life.

I have a 2006 expedition 5.4 the temp gauge stays on cold whats wrong?

check your coolant. the temp is the water temp. Your radiator is out of water? you`ll burn out your water pump. Also check to see if your radiator fans are running constantly.

Ohm c heck on removed pontiac G6 water temp sensor

you are trying to test, the readings should equal the temp, lets say like now you have it out it should read the temp of air, if you had it in the car and tested it with cold engine and then test as engine runs and coolant gets hot you would see the readings change, this way is okay if it reads the temp of the air but i would also do it installed with engine running .

Okay here is a chart. starting at 300 degrees
300* = 35ohms
210 = 185ohm
160 = 450 ohm
100 = 1600 ohms
70 = 3400
40 = 7500 ohms
20 = 13500
0 = 25000 ohms
-40 = 100700 ohms

  • There are more readings in between these temps but this should help i will enclose a web site if you need the other readings. this chart is good and readings have a + or - of 50ohms. good day. www.gmtemperaturesensorchart
