Your fan delay relay is not functioning. On most furnace fan controls, there is a fan delay relay that delay the fan from turning on until it senses the temperature increase, typically around 130 degrees. once the relay senses the temperature increase it closes a contact inside the sensor and turns the blower on. It is the same device that keeps the fan running once the furnace turns off. Just take the Model number and serial number to your local dealer and get a fan delay relay and replace it.
This is way out of my league, but here is some info that might help.
Before 1954 there was no uniform VIN number used in the USA.
In the years leading up to 1931 Chrysler Corp and a few other car companies used a FEDCO plate on the dash or firewall for the serial number ID of the car. The car was registered by this number by some states, and some used the engine number. Starting in 1931 the serial number was changed and moved to the door post. So a 1930 car should not have a plate on the door post.
The engine number was always stamped on the block. Also keep in mind 1931 Chrysler products were carried over into the 1932 model year, including Desoto.
The serial number depended on the make and model unlike cars of today. A series 31 model started with a number 6 or 8, while a series 32 model started with letters like SA or CFS, a series K started with the letter K, and so on. Actual serial numbers were seven digits.
On most models the serial number is also stamped on the frame near the front spring support.
You can do an internet search for DeSoto FEDCO numbers and serial numbers to get a general idea of how the serial numbers were arranged. You can also contact Chrysler Historical Society to see if they have the build card for your car. The build card would have both the original engine number and serial number. There are other resources including the Antique Auto Club of America.
This is a 30 Ton Hi Efficiency Gemini series unit from carrier
you can matched to either of these air handlers.
Model is broken down in sections
38AH = carrier Gemini series units from 20 to 120 tons the numbers following the dash represent the size
024 = 20
028 = 25
044 = 40
the list goes on in increments of 10 untill it reaches 130 tons
Hope this helps

if you have the model number of the furnace, then you have the btu input of the furnace. The model number usually starts with letters, then the three numbers following the letters are usually the btu input of the furnace.
For instance if it said 075 then it would have an input rating of 75,000 btu/hr or if it said 125 then it would have an input rating of 125,000 btu/hr.
there isnt a pilot if it has jets , it has a Hot surface ignitor. you should see a glow and then the jets light , if its running for a few min it may be overheating, have you changed the filter recently? you should also have a flash code you can locate when the furnace shut off and is no longer doin what its supposed to look thru the bottom door peep hole and watch for a series of red flashes. if you remove the cover after retrieving the flash code there will be a chart on the inside of the cover that will tell you why the furnace is shutting off. by the way the model # you gave is for the A/C coil above the furnace, not the furnace.
