MUNCHKIN High Efficiency Heater

[Deleted User]

The heater was installed about 2 years ago. The noise started as soon as the blower motor was replaced. If there's any small gap between the Ventori and the new blower motor could this be it. I have someone looking at it now and he thinks the cork gasket is missing. He can't see it when looking at the side??. I thought it was there when i replaced the motor.And I believe it is.. What needs to be cleaned and can I do this myself.

MUNCHKIN High Efficiency Heater

This is the M140. heater.. The blower motor was replaced and since then during operation startup there is a loud vibrationRumbeling noise. During slow speed there is whinning simalar to a Whale matting call. The blower motor pulls in the gas/air mixture and pushes it into the burner. I have had a few people in to look at this with no resolution. I have also talked with tech support at Heat Transfer, This is who makes the Munchkin.. They think I should have someone do a combustion analizer. Does this sound like the problem.. At my witz end.. Any sugestions.

Known issue?

Mike,

I own a Munchie as well..an 80M. I have not had the problem you describe but I've seen those symptoms posted on this site a number of times before.

I suggest using the search feature of this site and do a keyword search for 'Munchkin' or 'Munchkin fan'or 'Munchkin blower'...etc, you get the idea ).

Munchkin noise etc

How long has it been installed, if over a year it needs cleaning/service. On top of that, yes it does need analyzing with combustion analyzer no mater what. Good luck.

see my post in 2 yr old Munchkin 1/2 way down list

The first time at least it should be done by qualified mechanic and you watch closely to learn.
