is this your furnace
Doesn't seem like the click I wanted. To left of the draft motor is the draft proving switch. It is round silver disc with two wires to it. There is a small tuning connected to it also. Remove the tube and be sure it is clear, no water or debris. Gently blow into the tube toward the switch. you should here it click. Let me know
That sounds good. I think your hot surface ingnitor is bad. Do you have a voltage meter?
You need to test to see if there is voltage going to the igniter. If yes and doesn't glow it is bad. If no voltage something else is wrong. Let me know
Without a meter it is difficult, here is the sequence that should happen
1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds or so hot surface ingnitor glows.5 gas valve open and have ignition. 6.Flame sensor prove ignition.
If you jumped the draft switch and replace the ingnitor the only other thing is the circuit board which provides power to the ingnitor. check the board. Any burns marks? All wire connected properly?
blower on bottom blows up to duct work on basement celing to up stairs
Bottom panel near the blower?
There must be one higher up. Above the burner
That is a roll out switch. Can you follow the wire to see if it goes to another one.
I found this from the instruction manual
Lockout (see previous Numbers 1, 4, 5). The gas valve,
ignitor, and induced draft blower are de-energized immediately
(Exception: If a trip on high/auxiliary/rollout limit
is combined with a lockout, the induced blower will remain
energized until the limit closes.). The air circulator
blower runs for 90 seconds, and then shuts off.
To manually end a lockout, interrupt the call for heat for
at least 1 second, but not more than 20 seconds.
Turn the power off for 5 seconds then back on see what happens
Again from the manual. You have found the aux limit in the blower, the roll out near the burner still need to locate the priXXXXX XXXXXmit
Open Thermal Protection Device. If the primary (high)
limit, auxiliary limit, or rollout limit control opens, the
gas valve is de-energized. Both the induced draft blower
motor and air circulator blower are energized on low
heat speed. The diagnostic light code for this problem
is four short flashes followed by a longer pause.
If the primary or auxiliary limit is open, the probable
cause is either: low conditioned air flow due to dirty filter
or high resistance in duct work, faulty limit, faulty
blower, or blower speed set too low. The priXXXXX XXXXXmit
will automatically reset, while the auxiliary limit control
must be manually reset.
If the rollout limit control is open, the probable cause is
insufficient combustion air, restricted flue passage, or
restricted heat exchanger. The rollout limit control must
be manually reset.
6. Flame Sensed with No Call for Heat. If the co
There still is an upper or priXXXXX XXXXXmit. Follow the wire form the roll out switch.
Did you turn it off for 5 sec and back on?
check pages 127 and up
Great. There is no reset button on right?
If not it needs to be replace because it stuck open. After you replace it you need to watch the furnace cycle. Does it over heat and shut off on the limit switch? If it does something else may be wrong.
What is the condition of the air filter?
Good replace the limit and watch to see if it cycles off on high temperature while it is running. You should be able to get one where you got the hot surface ingnitor
Bet you never wanted to be that intimate with your furnace?

Learned alot, great help,
