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.
Number of flashes mean different things for diff models. The meanings of those flashes should be posted somewhere on the unit; usually inside front of the bottom service panel. Though you can't truly diagnose a problem by number of flashes they can give you an idea of where to look for a problem. There are a ton of videos and how-to's about furnaces on youtube by real service techs. Most modern furnaces have basically the same set-up and features so don't worry about your paticular brand; but of course that would be the best place to start looking. You could start here to familiarize yourself with your brand of furnace:
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
Best of Luck
Adhiinc, the model you posted is for an AC coil made by Goodman. You will need to post the Make and Model number for the air handler/furnace that this is connected too. You can find the model number if you remove the front panel and look on one of the sides for a label. Thanks and good luck!
If you have or can find the serial number of the furnace, you can contact Hunter directly and they can tell you the manufacture date. Their contact information should be on the Manufacturer's data plate on the furnace.
Great! That is it. Now you have the model numbers for all of your hac equipment.LOL. Anyway I do have this manual and I an send it to you via email if you like. It shows the jumper that I told you about as well as a picture of the circuit board and instructions on how to change the blower delay. Just shoot me an email. Good Luck!
I believe that this model number is for an air conditioner evaporator coil. This unit is probably directly attached to your furnace. The Model number for the furnace will be located in the compartment where the flames can be seen. It will be on a sticker or plate that contains lots of other information too like BTU/h, Volts etc...
The number you gave me gives me this info: Cased air conditioning evaporator coil. 3 Tons Horizontal application
