    JUST GOT HEATER OUT OF CLOSET. IS DOING THE SAME THING. WON'T STAY ON. JUST KEEPS KICKING OFF AFTER TURNING ON. SUCH A SHAME. ONLY 2 YEARS OLD. LIKE SOME OF THE OTHERS, WOULD COST A FORTUNE TO SHIP BACK PLUS THE $10 DOLLARS THAT YOU NEED TO SEND WITH IT. HAS ANYONE SHIPPED ONE? HOW MUCH DID IT COST?

I was having the same problem and did a search to find this link. This morning when I turned it on, I backed the temperature down to 66 when it first came on (defaults to 70) and it appears to be working now (it's been on for over 10 minutes)

I have a 70,000 desa master portable heater that will light and wont stay lit but for a few seconds i have a manual and cleaned as suggested but nada. i dont have the gauges needed for the pressure check....



By design HSI heaters:
  1. the glowbar (ignitor) only glows for 5 seconds the quits.
  2. Once the flame it ignited it perpetuates itself.
  3. If the photocell does not see the correct color of flame (rich/lean/none), it will send a signal to the control board to shut down.
This is true provided the fuel system and the electronicsare functioning properly. Now, you must troubleshoot the system to see if you have afuel delivery problem or an electronics problem. Always starttroubleshooting by checking the air pump pressure and proceed from there. Theheater will never run right if the pressure is + or - 1/4psi from specs. Maybe these tips will help http://www.reddyparts.com/HSI_tips.htm If the air pump pressure is dead-on the follow thesetroubleshooting tips http://www.reddyparts.com/HSI_tips.htm Good luck

Heater wont stay lit when i let go of primer button after a few seconds


try holding down the button for 15 to 20 seconds and then let go ( this will let the system heat up to the proper temp ),, if it still will not stay lit then the thermal coupling is bad and needs to be replaced.

Heater will fire but wont stay lit.


I assume that you are referring to a natural gas forced air furnace. If so you just described the symptoms of a dirty flame sensor. Remove the sensor with a 1/4" nutdriver. clean the flame sensor with a small piece of fine grit sandpaper or emery cloth. replace the sensor and turn the furnace back on.
Good luck.....

Wat the hell is wrong with my dayton heater?170,000 btu oil fired...wont stay runnin?on shut down puffs like a mutha....


Most use a spark plug to ignite fuel it could need cleaning. You also could have water in fuel or dirt
check and clean ignitor/spark plug clean fuel line and nozzle, drain and clean tank Check for water in fuel by tilting unit to have a low corner siphon fuel from that corner after 1 hr inspect for water.

The heater won't stay lit


Hi Tiffany,

When a gas applaince goes off it is usually because of a safety precaution. When the unit dies not detect a flame, it will shut off so that it does not fill with gas and cause damage. A flame sensor is a metal toothpick type item that is in the flame area and could be dirty, although it is two months old, this may be another problem.

But if it is charred, you will need to clean it using a soft cloth or even a well used dollar bill. Don't use abrasives, it will take the coating off of the part and cause it to wear faster.

If you are unsure, below is a link to the manufacturers website, you can get the technical information there.

The heater will not ignite properly


How old is the thermostat? Also there a limit switches at different points on that unit. If you have a volt ohm meter find the round disc like safety's and ohm them out. Take the wires off the disc before testing them. You should have a continuity should be closed they only open if unit gets too hot. Say something like 180 degree's.

A fast way to check out the thermostat is take a small diameter wire take the cover off the t-stat and jump across the R and the W on the t-stat. If the furnace comes on then t-stat bad. Let me know if this is helpfull. Ken

The heater will not ignite properly and the heater will not shut off


Judging by your pics (helpful, by the way) you have a high limit wired into your thermostat wire. Try disconnecting that wire nut connection in front of your valve and hooking the thermostat straight to the top and bottom posts on the valve (eliminating the high limit). If it runs fine, either the connection was poor or your high limit wire is pinched.
