The heater fan runs for about 5 seconds , does not heat and than turns off.

Have you waited long enough?
Sometimes it can take 5 -10 minutes before it turns on while using heater.

sounds like a leak in the air stack or if coming from gas valve need new gas valve

HI Lawrence did you check to see if you have the right power going
to the unit

I had the same problem and fixed it with a reset. The reset button is on the back of the remote next to the dip switches. You have to take the battery cover off to see it.

Turn on the fan with heat using the remote. Then, leaving the remote turned on, turn off the fan at the wall switch or circuit breaker. Wait a few minutes and turn the electricity back on. Then, within 30 seconds, and within range of the fan, press the reset button. You should be able to see a countdown from 5 to 0 on the remote screen.

Once I did this the heat began working again.

I had the same problem with my fan and solved it with a reset. The reset button is on the back of the remote next to the dip switches. You have to take the battery cover off to see it.

Turn on the fan with heat, even though the heat doesn't work. Then, leaving the remote on, turn off the fan at the wall switch (or circuit breaker box). Wait a few minutes. Then turn on the power and within 30 seconds, press the reset button. You should be able to see a countdown from 5 to 0 on the remote screen.

Once I did this the heat started working again.

Mine has two switches one says cool - off - heat, the other says fan on - fan auto. For heat I set the first to heat and the second to auto. This puts everything in to heat mode and the fan runs from the furnace control now not constantly. Hope this helps you out.

This will be due to a finicky blower relay. Whether on a circuit board or stand alone....the blower relay will be your issue

brivis wombat 2P 20 ducted heater, gas fires up but fan not starting
Any suggestions...???

your blower motor is trying to seize up on you, it is time to change it, if the fan doesn't come on first your water heater should not light, the fan comes on first to get eccess gasses out of the burner compartment,, do not light with ot the fan first it could combust
