With a capillary-tube thermostat, swings like that usually mean the thermostat is wearing out, or the bulb has moved from its spot on the fins. Make sure the tube is still clipped where it belongs. I can't confirm a replacement thermostat for the 838EG2 from here.
Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you. You can also browse www.rvfridgeguys.com.
