I have an old caloric gas oven , model # rmd 269 UW, that I am having trouble with. The burners work fine but the oven does not want to heat up to the tempurature it is supposed to be. It is a lot cooler than what it is set at. I have a small manual and it says to check make sure the thermostat capillary bulb (in the top of the oven) is in the correct straight position, not touching the sides of the oven and clean. It also says to make sure the vent is not blocked. Should I be able to see this capillary bulb in the top of the oven and if nothing is wrong with it could there be anything else I can check? Is there any kind of thermostat that may be broken?

Hello barney5116 and Welcome to the Do It Yourself Web Site and my Gas Appliances topic.
The capillary tube (bulb) is the element that is inside the ovens baking compartment and supported by two clips. May be hanging in full view or have a cover over it to protect it from being damaged, etc.
Capillary tube (bulb) must not be touching any other metal part except the clips that hold it in place. And yes, capillary tube must be in a straight position. All that is you mentioned that is in the book is correct.
The vent is also inside the ovens baking compartment on the top wall. Be sure nothing is blocking that area and nothing blocking or restricting the exhaust vent outside the oven. Air must flow freely as designed into and out of the baking compartment with the oven door closed.
If the temp is too low constantly with every usage, most likely, providing all the above is correct and the gas valve is working correctly, etc, the thermostat is defective.
How difficult it will be to remove the thermostat and replace it depends on it's type. Several types used in older stoves (ovens) with several different types of pilot assemblies and safety devices designed into them.
More specific info on how to remove and replace the T-Stat and typical types of problems and the solutions likely to be obtained at the local appliance parts store. That model is not visable online to see pictures of.
