Air parking heater

[KAM]

My new heater didn't work due to error 01 temperature sensor open circuit. It measured as open circuit on the 2k setting on my meter. New sensor arrived today. It measures 70k ohm which seems a lot more than the 1 K I was expecting. Going back to the old sensor it also reads 70k ohm. Rechecked many times. Anyone know what the sensor technology is could someone who has actually checked confirm what temperature sensor resistance they measured. I am presuming both are failed and that this is the mode of failure. Glad I decided not to remove the Taylors.

Useful to know which heater.
My ebers have the following values

Overheat sensor around 30kOhms at 30degreesC but around 70kOhms around 18C
Flame sensor around 1100Ohms at 30 degrees

Which heater did get the code is different for other makes.

It's one of the Chinese ones. It's the overheat sensor on the heat exchanger. I thought it was supposed to be 1k but looks like wrong part may have been fitted somewhere.

Poor internal connection to the sensor, perhaps?

The fault code 01 on the chinese heaters is low battery voltage,could also be set to 24v

Thanks peteK. That's probably it. I looked it up on line and assumed they were all the same. There's a lot of confusing information out there.

Almost all the common temperature sensors are NTC thermisters - so if they are open circuit/missing then the heater interprets that "high" resistance as something silly like -50C !

When I fitted mine China heaters facebook page was useful and utube videos.

The indoor temperature sensor TA may be faulty.
