If a stove were required, why would the URAR have a check a box if it exists. If a stove were always required, there would be no need for the box. If there is vent hood and stove the appliances must be checked for operation, but there is no requirement for having them in the current handbook - see a searchable version below.
An exhaust fan may fall under the Safety requirement if there is a local building code requiring exhaust fans. Again, FHA does may not have a specific requirement for an exhaust fan, but the property must meet minimum building code requirements for the area. As an FHA Certified Appraiser, I spend a lot of time researching and understanding local building codes as they pertain to each property - that's why I get paid the big bucks lol ;-)
While I've heard that guidelines have changed I have not experienced it. If the house is missing the stove it will be required in order to close. I've had 2 buyers in the last month that have gotten hung up because the houses were missing a toilet (even though there were 2 other functioning toilets in the houses). Sometimes, the REO lender will make FHA necessary repairs. Otherwise, it's that catch-22, you can't close because it's missing something and the bank won't put it in and they can't allow you to put it in. My recommendation is to ask the lender to replace it if you are still within your inspection period. Your next best option is Craig's List. Slap in a stove and fan and have a re-inspect done by the appraiser.
Keep your eyes out for those items when writing offers and good luck!

Easiest thing to do is just replace the stove!
The only repairs required, are for conditions that rise above cosmetic defects, minor defects, or normal wear and tear. It is not the appraisers decision wether or not to complete the appraisal due to the lack of appliances, and the lender and/or underwriter should use professional judgement and underwriting practices to determine if the condition is a threat to safety or jeopardizes structural integrity.
