It sounds like you have bad DC filter caps in the power supply, when its cold the ESR (Equivalent Series Resistance) will go up if you have bad cap, goes down when it is warm up, I use hair dryer for locating bad caps, and small low watt soldering iron for heating up individual cap once the general area is located by hair dryer, this trick is 30 years old! You can see ESR goes down when heated if you have cap meter with ESR testing function.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Is it normal for my furnace to have burner cycle once or twice


That sounds normal. When the bonnet reaches a preset temperature the burner turns off then when it cools down a bit the burner turns back on. Clean filters etc will help to keep the burner on longer in a cycle.

Dyson hot and cold fan only works in hot mode


Hi there, it's Jack at Dyson.

When you adjust the target temperature of your Dyson Hot fan heater (shown on the LED display on the base), you're setting the target temperature you would like the room heated to. The actual temperature of airflow produced by the fan heater will not vary.

If the heater won't run below 25 degrees, this is likely to be because the temperature of the room you're in is equal to or warmer than 25 degrees. The heater will only turn itself on if the temperature drops below 25 degrees, and once the room temperature reaches this target once again, the fan will turn itself back to monitoring mode.

I've attached our Getting started video below which shows how to adjust the temperature, using the remote or the controls on the base.

I hope this makes sense. It sounds as if your machine is working correctly, but if you'd like any further advice from our experts you can reach us at 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Definitely a thermostat.It has 2 sections.One is a temperature reference section(what temp you want).The other is the temp reading section.If either one is bad,it will do just like you said.Sounds like the reference section is probably bad because it comes on for a couple minutes then shuts down.Since it was fine earlier in the day,I doubt there is anything wrong with the furnace because as you can see,it is temperature related.A furnace problem would be more of no operation at all,even if just dirty or whatever.The thermostat also would be a more common 'fail component' than the board.A suggestion also,both for a car and a house.During the summer,run the heat for 2-3 minutes,just to cycle it occasionally.In winter,run the A/C for 2-3 minutes.Do both perhaps once or twice a month.It helps keep the components,somewhat fresh I guess you would say,because cycling it occasionally helps to keep it going good.Also,if you encounter a problem,you may be able to get it fixed before you really need it.In the meantime,feel free to come on down to FL until it's fixed,we have room,lol.Although it's chilly now,the weekend will be 70's.(sorry)Good luck,Greg

Makes a crackling sound while running


If the room tempature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defost over night.
Only specially made dehumidifers work below a room temo of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensot from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.
