Cpc-610A won't allow to menu to right side which includes, high slow cook...only stays on left side as I press menu

If timing does not allow the recipe to be cooked on low for as long as required, the slow cooker can be turned up to high and the cooking time reduced. Convert cooking time by using a ratio of 2 hours of cooking on low as being equal to 1 hour of cooking on high.

it is possible that you have misunderstood the instructions
for a slow cooker you have low medium and high
press slow cook and on low and in 8 hours the food is cooked
I see from your statements that you expect the cooker to be set on slow cook but cook at a high temperature fast
if it says slow cook --9 hours and the temp is 125 degrees , have you waited 9 hours to see if it is cooked as the slow cooking process is by the gradual build up of heat in the container that is not expelled by radiation to the air
in a pressure cooker , that build up of heat also builds up pressure and so it cooks better
other solution--- if it is not right return it for a warranty refund or if out of warranty , junk it and get a different make

it is a slow cooker for the purpose of slow cooking so turn it to low and it will keep cooking
If you want fast cooking on high temp use a pot or a pan .it will be cheaper.

From the Hamilton Beach website:Q Should I close the clips on my Stay or Go slow cooker during cooking?A We recommend closing the clips only during transport and storage. Closing the clips during cooking will not allow for proper ventilation of steam.

make sure u DO NOT lock the clips while cooking, its not a pressure cooker. if you lock the lid the heat and pressure from whatever you are cooking causes an air-tight seal and the lid will shatter or the ceramic pot it self will crack...

This slow cooker has 3 settings LOW, HIGH, & WARM
