Yeti 1500X showing under temperature

My Yeti 1500X regularly shows being under temperature, at which point the app indicates the temperature being sub-zero (Celsius) and it will not charge. The unit is kept at room temperature (20-25 Celsius). Sometimes when the 240V output is loaded (>1kW) it can bring the apparent unit temperature back to something sensible and allow charging, but this is intermittent. GoalZero cannot provide any support as I'm in the UK - is there any information on troubleshooting and repairing what is presumably a faulty temperature sensor or circuit?

Hi @nrw

Try a reset (soft and factory - one at a time and check in between resets) and also check that the firmware to up to date and see if that resolves the problem.

Thanks - I've tried both soft and factory resets, and also done a battery reset (press and hold RESET and INFO for 5 seconds). Firmware is on the latest version (1.8.9).

@nrw

best that I can find out is the the temp sensor is a thermistor hard mounted in the BMS section (Battery Management System) on a board in the unit.

As to its specifications idk.

How old is the unit?

There's a 2 year manufacturer's warranty which should apply even if not directly supported by Goal Zero, then by the seller from where you got it.

Unfortunately it's 4 years old so definitely out of warranty. Thanks anyway.
